1. Introduction
In the recent years, the chemistry of 2-chloroquinoline-3-carbaldehydes has received considerable attention
owing to their synthetic and reactions versatility, in addition to a wide variety of biological activity.1 These
aldehydes were also used as synthetic intermediates for the preparation of large numbers of heterocyclic
systems2 and stereoselective ligands3,4 of various importance.
Polyfunctionalized heterocyclic compounds play important roles in the drug discovery and drug analysis
processes; about 68% of available market drugs are containing heterocyclic ring system.5 Hence it is not
surprising that research on the synthesis of polyfunctionalized heterocyclic compounds has received
significant attention. The quinolone or 1-azanaphthalene ring system represent a wide occurrence in the
nature as substituted and fused ring derivatives, Its derivatives have been known to display a wide range of
pharmacological activities such as antimalarial6, anti-bacterial7, anticancer8, antifungal9, anthelmintic10,
cardiotonic11, anticonvulsant and antihypertensive12, anti-inflammatory and analgesic activity.13 In addition,
Quinoline has a privileged scaffold in cancer drug discovery.14 2-Chloroquinoline-3-carbaldehydes has been
reviewed during the period from 1979 to 199915 and from 1999 to 201116, Herein, in this review, we cover the
versatile synthetic methods and reactions from 2012 until 2017.

3.1.2. Cyclization at aldehyde group. A new series of quinoline-based azetidinones 26a-l and thiazolidinone
27a-l analogs was developed by a simple and efficient synthetic protocol. The thione nucleus was obtained
from 2-chloroquinoline-3-carbaldehyde I using sodium sulphide in DMF followed by reaction with various
substituted amine to form the corresponding Schiff base intermediates 25a-i. Attempt has been made to
derive final azetidinone and thiazolidinone analogs from Schiff’s bases by using chloroacetyl chloride and 2-
mercaptoacetic acid, respectively (Scheme 9).31

The aforementioned procedure was further applied via one-pot reaction of 2-chloroquinoline-3-
carbaldehydes I, 6-aminouracils 38 and dimedone 37. Interestingly, the 6-Me and 6-OMe substituted quinoline
aldehydes gave rise to products 40a-c proceeding through intramolecular nucleophilic attack by nitrogen,
while the other aldehydes gave products 39a-d resulting from attack by oxygen. The exact reason for this
selectivity is at present unclear (Scheme 13).35

Synthesis of highly substituted cyclopentadienes containing quinoline nucleus 46a-j, was described.
The initially prepared Knöevenagel adducts 43a-b of 2-chloroquinoline-3-carbaldehydes and malononitrile or
ethyl cyanoacetate underwent reaction with acetylenecarboxylates 44a-b and isocyanide 45a-b in
dichloromethane at room temperature within 12 h, affording the products in moderate to good yields. Mild
reaction condition and prompt isolation of the products are some advantages of this protocol (Scheme 15).37

When the aldehyde I was reacted with urea or thiourea 47a,b and active methylene compounds 48a-b
in ethanol and in the presence of drops of acetic acid as a catalyst in one-pot reaction namely Biginelli
reaction38,39, the corresponding compounds 49a-b and 54a-b was obtained respectively. The carbohydrazide
50 was afforded by reaction of hydrazine hydrate with the ester derivative 49b. Moreover, condensation of
49a with 2-aminophenol 51 in the presence of acetic acid afforded the tetrahydropyrimidine-5-carboxamide
derivative 52; while the carbimidate derivative 53 was afforded, if the same reaction was carried out in
ethanol (Scheme 16).40

Via Sonogashira conjoined electrophilic cyclization, the three component reaction of o-halo aldehydes
I, alkynes 58a-e and tert-butylamine 59 led to the synthesis of biologically active benzo[b][1,6]naphthyridine
derivatives 60a-h, using a bimetallic Pd/Cu catalytic system. (Scheme 18).42

A facile and efficient method for synthesis of novel furylquinolines 62a-r was developed via the
condensation of 2-chloroquinoline-3-carbaldehydes I with acetylenecarboxylates 44a-b and isocyanides 56a-b
and 61. The mixture was stirred in acetonitrile for 12 h at 40 oC. After completion of the reaction, the mixture
was cooled to room temperature to afford 62a-r (Scheme 19).43

3.1.3.2. Four component reactions. A convenient and facile method for synthesis of diverse quino[2,3-
b][1,5]benzoxazepines 66a-t was developed. The reaction proceeds through a one-pot sequential Ugi-
4CR/base-free intramolecular aromatic nucleophilic substitution reaction (SNAr) in moderate to good yields
from readily available starting materials. Upon treating 2-chloroquinoline-3-carbaldehyde I with 2-
aminophenol 63a, acetic acid 64a, and cyclohexyl isocyanide, 65a was directly obtained as a sole product in
83% yield (Scheme 20).44
Also benzo[b][1,8]naphthyridine derivative 36{7,1,5} were obtained in low yield (42% yield) via four-
component reaction of 6-tert-butyl-2-chloroquinoline-3-carbaldehyde I(7), 4-hydroxycoumarin 34(1),
dimedone, and aniline. After completion of the reaction, the reaction mixture was cooled to room
temperature. The crystalline solids were collected and purified by recrystallization from DMF and water to give
pure products 36{7,1,5} (Scheme 21).34
In an extended work at the same context, the synthesis of diverse naphthyridinone derivatives 68a-h
was presented. When 2-chloroquinoline-3-carbaldehydes I, 3-methyl-1H-pyrazol-5(4H)-one 67, enaminone 35,
L-proline was stirred and refluxed in ethanol (Scheme 22).45

around 3-cyanopyridine derivatives 73a-f and 74a-d from 2-chloroquinolin-3- carbaldehydes I, acetophenone
derivatives 72, active methylene compounds 69a-b, and ammonium acetate as a source of ammonia in the

The synthesis of a new series of 2-chloroquinolin-3-yl ester derivatives 77a-i was reported via a two-
steps protocol from 2-chloroquinoline-3-carbaldehydes I. Firstly, I was reduced using NaBH4 in methanol to
yield the corresponding alcohol derivatives 75a,b,e, which is then reacted with acid chloride in DMF along with
activated K2CO3 at room temperature to afford target compounds (Scheme 26).49

The quinolinyl methanol 79, when allowed to react with methane sulfonyl chloride in presence of TEA
in DCM at 0 °C, yielded the corresponding tetrazolo[1,5-a]quinolin-4-ylmethyl methanesulfonate ester 80,
which on condensation with p-hydroxybenzaldehyde in DMF in presence of K2CO3, afforded the required
precursor aldehyde 81. One-pot cyclocondensation of the 81 with anilines 82a-l and mercaptoacetic acid 83
was carried out in PEG-400 at 110 °C to obtain the thiazolidin-4-ones 84a-l in moderate to good yield (Scheme

The synthesis of a novel series of substituted 1,4-dihydropyridines 107a-k was achieved in aqueous
media by a base-catalyzed Hantzsch reaction of 2-chloroquinoline-3-carbaldehydes (I and 105f,g), ammonium
acetate, and alkyl acetoacetate 106a-b in good to high yields was achieved (Scheme 38).60
Functionalized 2-amino-4H-benzo[b]pyran 42c and 108, dihydropyridine 107a, polyhydroquinoline 109,
derivatives were synthesized at ambient temperature in aqueous medium, in the presence of Bi2WO6 (5 mol
%) as a catalyst. Bi2WO6 nanoparticle mediated multicomponent reactions (at RT, in aq. medium) afforded
good yields in a short period of time (10–45 min; 5 mol% of catalyst) (Scheme 39).61

3.4.2. Reactions with hydrazine, hydroxylamine, hydrazides, (thio)semicarbazide, and urea. The synthesis of
new series of quinolinyl Schiff’s bases and azetidinones was reported. The aldehydes I, upon treatment with
methanol in the presence of KOH furnished the corresponding 2-methoxyquinoline-3-carbaldehydes 114a-d.
The Schiff’s bases 115a-d and 116-d were prepared by reacting 114a-d with isoniazid and 4-(1H-pyrrol-1-
yl)benzohydrazide in the presence of glacial acetic acid, respectively. While the Schiff’s bases 117a-d were

prepared by reacting I with isoniazid in ethanol in the presence of glacial acetic acid. Compounds 115a-d,
116a-d, and 117a-d upon treatment with monochloroacetyl chloride in the presence of TEA in dry benzene
gave 118a-d, 119a-d, and 120a-d, respectively (Scheme 41).64

phenyl hydrazine 123a-c in MeOH at room temperature over 2-15 h, while the second method is in solid state
by grinding reactants to form products in short time (Scheme 43).66
Scheme 43
Dry grinding of a mixture of the aldehydes I and 4-methylphenylhydrazinium chloride 123d afforded
the hydrazone derivative 125(A,B), while the same reagents in methanol in the presence of sodium
cyanoborohydride gave the 1H-pyrazolo[3,4-b]quinoline 127a (Scheme 44).66,67

Similarly, the different hydrazides 132a-i were synthesized starting from aromatic acids 131a-i. The
benzohydrazide derivatives 133a–i were synthesized by reacting the aldehyde I and the appropriate hydrazide
132a-i. In the final step, the oxadiazol-2-ylquinolines 134a-i were synthesized with chloramine-T as
aforementioned (Scheme 46).68,69

tolyloxy)quioline-3-carbaldehyde 136 was used as a starting aldehyde. This series had also been synthesized
using chloramine-T and refluxing in ethanol. The study revealed that compound 159 is a potent lead

When carbaldehyde I was treated with formamide and formic acid, the pyrrolo[3,4-b]quinolin-3-one
179 was obtained, the reaction occurs via Leuckart reaction70 by using formamide as a formylating agent. On
treating I with hydrazine hydrate, the hydrazone 180 was afforded, which then treated with aromatic
aldehydes 181 and 183 to give 3-((naphthalen-2-yl/1H-indol-3-yl)methylene)hydrazono)methyl)quinoline 182
and 184, respectively (Scheme 51).40
Furthermore, the carbaldehyde group in I was transformed to a nitrile group via condensation reaction
with hydroxylamine hydrochloride and sodium acetate to afford oxime 185. Dehydration of the aldoxime 185
with thionyl chloride gave the cyanoquinoline 186. The cyanoquinoline 186 was reacted with lithium
aluminium hydride and potassium sodium tartarate in THF afforded the corresponding amine 187. In addition,
cyclization of 186 with hydrazine hydrate afforded 188. Compound 190 was obtained from the reaction of 188
with benzoylisocyanate 189. In the same manner pyrazoloquinoline Schiff’s base derivatives 191 and 192 were
obtained in moderate yield by condensation reaction of 188 with naphthaldehyde 181 or indol-3-aldehyde 183
(Scheme 52).40

3.4.3. Reactions with amines and amides. 2-Chloroquinoline-3-carbaldehyde I was reacted with amines 193a-
c to form an imine intermediate, which was subsequently cyclized to afford tetracyclic thio- and oxazepino
derivatives 194a-d.71-73 While benzo[2,3][1,4]thia- or oxazepino[7,6-b]quinolones 195a-i was afforded by
reacting carboxylic acid, isocyanide and 194a-d in methanol. The reaction mixture was stirred for 48 h at room

A mixture of 2-oxoquinoline-3-carbaldehyde 222 and stabilized ylides 218b-d in absolute ethanol was
stirred at room temperature for 2 h. The formed colorless precipitate was filtered and recrystallized from
absolute ethanol to give the corresponding Z-223b-d isomers. Pure Z-223b-d were obtained by
chromatography (Scheme 60).79

The behavior of compounds E,Z-219c toward hydrazine hydrate was also investigated. In which
hydrazine hydrate was added to a solution of compound Z-219c and/or E-219c in ethanol. The reaction
mixture was heated under reflux for about 3h. The solvent was evaporated under reduced pressure and the
residue was recrystallized from chloroform/n-hexane to give 3-(2-chloroquinolin-3-yl)propanehydrazonic acid

Scheme 61
On the other hand, heating under reflux a mixture of E-219a or E-219d with the appropriate secondary
amine (morpholine 225a or piperidine 225b) for 7–10 h, followed by evaporation of the volatile materials and
triturating the residue with diethyl ether afforded colorless 226a-d (Scheme 62).79
Scheme 62
Finally, a direct and efficient approach to the synthesis of benzo[g][1,8]naphthyridines 228a-d, 230a-d
from simple synthons 2-chloroquinoline-3-carbaldehydes I, 1H-Indazole-6-amine 227 and 2-chloroquinolne-4-
amines 229a-b, has been developed. The reaction proceed by simple condensation under basic medium
conditions without any catalyst furnishing the naphthyridine derivatives 228a-d and 230a-d, respectively
