Description

A kind of asymmetric catalytic hydrogenation method of ketone deutero-N-alkyl imines
Technical field
The present invention relates to the method for the asymmetric catalytic hydrogenation reaction of imine compound, particularly relate to a kind of asymmetric catalytic hydrogenation method of ketone deutero-N-alkyl imines.
Background technology
Asymmetric efficient the synthesizing of high enantioselectivity chipal compounds, in chemical industry, agricultural, herding and each field of medicine, be subjected to common concern day by day, especially at pharmaceutical industry, the research and development of chiral drug, production and selling have become the main flow (A.M.Rouhi of global medicine industry development, " Chiralchemistry ", Chem.Eng.News 2004,82, and 47).And asymmetric catalytic hydrogenation is one of main method of efficient production chipal compounds.The asymmetric catalytic hydrogenation reaction is meant at chiral catalyst and (is generally the title complex that chiral ligand and transition metal form, X.Zhang, " New ChiralPhosphorus Ligands for Enantioselective Hydrogenation ", Chem.Rev.2003,103,3029) under the effect, hydrogen generates chiral product to the addition reaction of unsaturated link(age) in the unsaturated prochirality compound (being called substrate).Unsaturated prochirality compound generally comprises prochiral olefin (C=C), ketone (C=O), imines compounds such as (C=N).The asymmetric catalytic hydrogenation reaction is because of using hydrogen cheap and easy to get, and little to the pollution of environment, chiral product has high enantioselectivity again, so be subjected to the generally attention of industry member.As far back as the seventies in last century, suitability for industrialized production (the H.U.Blaser that U.S. Monsanto Company just utilizes the asymmetric catalytic hydrogenation technology successfully to develop to treat Parkinsonian L-DOPA, F.Spindler, M.Studer, " Enantioselective catalysis in fine chemicals production ", Appl.Catal.A:General 2001,221, and 119; W.S.Knowles, " Application of Organometallic Catalysis to the Commercial Production of L-DOPA ", J.Chem.Educ.1986,63,222; W.S.Knowles, " Asymmetric hydrogenations ", Adv.Synth.Catal.2003,345,3).
The asymmetric catalytic hydrogenation reaction of imines (containing the two keys of C=N) compounds is the easiest method (T.C.Nugent of preparation Chiral Amine analog derivative, Chiral Amine Synthesis:Methods, Developments and Applications (Ed.:T.C.Nugent), Wiley-VCH, Weinheim, 2010).All contain the Chiral Amine primitive in the skeleton structure of many bioactive compoundss and chiral drug, for example: among the formula I (1S, 4S)-sertraline (W.M.Welch, A.R.Kraska, R.Sarges, B.K.Koe, " Nontricyclic antidepressant agents dedrivedfrom cis-and trans-1-amino-4-aryltetralins ", J.Med.Chem.1984,27,1508) be a kind of effective antidepressant drug, Compound C inacalcet (O.R.Thiel, C.Bernard, W.Tormos, A.Brewin, S.Hirotani, K.Murakami, K.Saito, R.D.Larsen, M.J.Martinelli, P.J.Reider, " Practical synthesis of the calcimimetic agent, cinacalcet ", Tetrahedron Lett.2008,49,13) and NPS-586 (A.Kessler, H.Faure, C.Petrel, D.Rognan, M.C é sario, M.Ruat, P.Dauban, R.H.Dodd, " N 1-Benzoyl-N 2-[1-(1-naphthyl) ethyl]-trans-1,2-diaminocyclohexanes:Development of4-Chlorophenylcarboxamide (Calhex 231) as a New Calcium Sensing Receptor Ligand Demonstrating PotentCalcilytic Activity "; J.Med.Chem.2006; 49; 5119) all can regulate the content of blood calcium, be used for the treatment of osteoporosis.Though the reaction of the asymmetric catalytic hydrogenation of imines has obtained extensive, deep research, and be acknowledged as the best approach of synthesizing optical homochiral aminated compounds, but compare with the asymmetric catalytic hydrogenation of prochiral olefin and ketone compounds, imine compound because of the existence of its cis-trans-isomer, relatively poor chemical stability and amine impurity and product to possible the poisoning effect that catalyzer exists, make the asymmetric catalytic hydrogenation of this type of prochirality compound react and also lack systematic research.In the report of the asymmetric catalytic hydrogenation reaction of existing imines class substrate, the asymmetric hydrogenation of ketone deutero-N-alkyl imines especially has only the chiral metal catalyst of a few transition metals and chiral ligand formation can this type of reaction of catalysis.Wherein employed chiral ligand is most of for containing the phosphine chiral ligand, and the enantioselectivity and the also relatively low (C.N.Thomas of catalytic efficiency of the reaction of imines asymmetric catalytic hydrogenation, E.-S.Mohamed, " Chiral Amine Synthesis-Recent Developments and Trends for Enamide Reduction; ReductiveAmination, and Imine Reduction ", Adv.Synth.Catal.2010,352,753).Recently, Chinese Academy of Sciences Shanghai organic fourth Kui Ling group with iridium metals chirality P-N title complex as catalyzer, realized the asymmetric catalytic hydrogenation of the high enantioselectivity of a series of ketone deutero-N-alkyl imines, the enantiomeric excess of 13 kinds of N-alkyl hydrogenation of imines products is all between 89%-98%, be the highest (Z.Han in the bibliographical information so far, Z.Wang, X.Zhang, K.Ding, " Spiro[4,4]-1; 6-nonadiene-Based Phosphine-Oxazoline Ligands for Iridium-CatalyzedEnantioselective Hydrogenation of Ketimines ", Angew.Chem.Int.Ed.2009,48,5345).The imines asymmetric catalytic hydrogenation has been successfully applied to large-scale industrial production, wherein, the most successful industrialization example is suitability for industrialized production (the H-U Blaser of chirality weedicide (S)-metolachlor of successfully developing of Syngenta company, " The Chiral Switch of (S)-Metolachlor:A Personal Account of anIndustrial Odyssey in Asymmetric Catalysis ", Adv.Synth.Catal.2002,344,17).They adopt the asymmetric hydrogenation of iridium-chiral diphosphine ligand catalyzer (Ir-xyliphos) catalysis imines key intermediate as gordian technique, and efficient (turn over number TON reaches 2,000,000, and transformation frequency TOF reaches 400,000h -1), highly selective realized present known largest asymmetric catalytic hydrogenation process with 10,000 tons/year output.In addition, Japanese Daiichi company and DOW Chemical (Dowpharma) have also successfully realized the broad-spectrum antibacterials levofloxacins (suitability for industrialized production of (S)-levofloxacin) and treatment Alzheimer's disease medicine (S)-18986 by the asymmetric catalytic hydrogenation gordian technique of imines respectively.
In the research of asymmetric catalytic hydrogenation, except that chiral phosphine ligand, non-phosphine chiral ligand (as: chirality amine part and chiral beta-alkamine part) also is the crucial part of a class, and than chiral phosphine ligand stability high, synthetic simple, price is relatively cheap.At present; the Chiral Amine part; especially chiral diamine ligands has been widely used in the multiple asymmetric reaction, such as protonated, the conjugate addition reaction of the acidylate of: transfer hydrogenation, Mukaiyama aldol reaction, Michael addition reaction, the reaction of Sharpless bishydroxy, alcohol, enol negative ion,
Epoxidation Reaction of Alkenes etc. (J-C Kizirian, " Chiral Tertiary Diamines in Asymmetric Synthesis ", Chem.Rev.2008,108,140).Though chiral diamine ligands and transition metal (such as: ruthenium, rhodium and iridium) catalyzer that forms has been widely used in the transfer hydrogenation of ketone and imine compound (transfer hydrogenation has been the reduction reaction that adopts the hydrogen source beyond the hydrogen to carry out, hydrogen source comprises: Virahol, formic acid-triethylamine azeotrope, sodium formiate etc.), and become one of high efficiency method (the S.Gladiali and E.Alberico of synthesis of chiral secondary alcohol and Chiral Amine, " Asymmetric transfer hydrogenation:chiral ligands and applications ", Chem.Soc.Rev.2006,35,226), but the application in asymmetric catalytic hydrogenation of chiral diamine ligands and chiral metal catalyst thereof only has several example reports, comprising quinoline substrate (H.Zhou, Z.Li, Z.Wang, T.Wang, L.Xu, Y.He, Q-H Fan, J.Pan, L.Gu, A.S.C.Chan, " Hydrogenation of quinolines usinga recyclable phosphine-free chiral cationic ruthenium catalyst:Enhancement of catalyst stability and selectivity inan ionic liquid ", Angew.Chem.Int.Ed.2008,47,8464; Z-W Li, T-L Wang, Y-M He, Z-J Wang, Q-H Fan, J.Pan, L-J Xu, " Air-Stable and Phosphine-Free Iridium Catalysts for Highly Enantioselective Hydrogenation ofQuinoline Derivatives ", Org.Lett.2008,10,5265; Z-J Wang, H-F Zhou, T-L Wang, Y-M He, Q-H Fan, " Highlyenantioselective hydrogenation of quinolines under solvent-free or highly concentrated conditions ", Green Chem.2009,11,767), imines (C.Li, J.Xiao in the ring, " Asymmetric Hydrogenation of Cyclic Imines with an Ionic Cp*Rh (III) Catalyst ", J.Am.Chem.Soc.2008,130,13208), acyclic N-aryl imine (C.Li, C.Wang, B.Villa-Marcos, J.Xiao, " Chiral Counteranion-Aided Asymmetric Hydrogenation of Acyclic Imines ", J.Am.Chem.Soc.2008,130,14450) asymmetric catalytic hydrogenation, and the asymmetric hydrogenation of the catalytic ketone deutero-of chiral diamine metal complexes acyclic N-alkyl imines and the outer N-alkyl imines of ring also rarely has report.
Ikariya groups in 2009 have reported the asymmetric catalytic hydrogenation reaction (S.Shirai of the catalytic aryl ketones deutero-of unique one routine chiral diamine metal complexes acyclic N-alkyl imines, H.Nara, Y.Kayaki, T.Ikariya, " Remarkable Positive Effect of Silver Salts onAsymmetric Hydrogenation of Acyclic Imines with Cp*Ir Complexes Bearing Chiral N-Sulfonylated DiamineLigands ", Organometallics 2009,28,802).In this piece article, the asymmetric catalytic hydrogenation reaction of aromatic ketone deutero-acyclic N-alkyl imines only has been discussed, do not comprise alkyl ketone deutero-acyclic N-alkyl imines class substrate; And the enantioselectivity of the asymmetric catalytic hydrogenation of aromatic ketone deutero-acyclic N-alkyl imines reaction is lower, and the enantiomeric excess of product only is 35%-72%, does not reach industrialization demands far away.
