Abstract
A 3-substituted 1, 2, 3, 4-tetrahydro-quinoline derivative, its synthesis and use are disclosed. The procedure is carried out by condensing substituted-o-nitrobenzaldehyde or o-aminobenzaldehyde with aryl-acetonitrile derivative, reducing by double bond and obtaining 3-substituted 1, 2, 3, 4-tetraquinazine derivate by loop closing under the condition of catalytic hydrogenation. It can be used for cerebral local ischemia, suppressive vasorelaxation, antiarrhythmic and antineoplastic activities. It is simple, has gentle reactive condition and more output.
Description
Technical field
The present invention relates to 1,2,3 of 3-replacement, 4-tetrahydroquinoline derivative and preparation method and use thereof, more specifically, relating to 3 is 1,2,3 of aryl replacement, 4-tetrahydroquinoline derivative and preparation method and use thereof.
Background technology
Tetrahydroquinoline and tetrahydroisoquinoline extensively are present in nature, and 1,2,3, the 4-Tetrahydroquinolinesas has vasorelaxation, anti-arrhythmia and the antitumor isoreactivity of inhibition, also has the effect of immunosuppressor, also is the dyestuff intermediate that has more characteristic.
A lot of tetrahydroquinoline derivatives are considered to very strong affinity ligands on the DMAD acceptor glycine position, it also is the convenience factor of norepinephrine transmission, still do not influence the myotility sensitive agent of metabolic defect in cellular calcium ion running simultaneously, therefore be potential drug (the Alan R.Katritzky et al. that treats diseases such as cerebral ischemia, Tetrahedron.52,48,15031-15070,1996).
The synthetic method that this compounds is commonly used has: the three component condensations that the aniline of replacement, aldehyde and electron rich alkene participate in obtain quinolines, and the quinolines that obtains is reduced or catalytic hydrogenating reduction with the active metal.These method of reducing condition harshnesses, not easy to operate, and also the diversity of quinoline is subjected to the considerable restraint of synthesis condition, is difficult for making by known method as the 3-aryl quinoline, and then just more is difficult to prepare 3-aryl-1,2,3,4-tetrahydroquinoline derivative.
