Synthesis of diethyl 4-(phenyl-substituted)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylates catalyzed by CoCl2/K-10 montmorillonite in water and their antimicrobial activity
摘要:
A simple and efficient method of one pot synthesis of 1,4-dihydropyridine by three components reaction of aromatic aldehydes with 1,3-dicarbonyl compound, ammonium acetate and catalytic amount of CoCl2 based on the Hantszch reaction is developed. The process is catalysis by an inexpensive catalyst in water medium, gives high yield of products and involves no volatile organic solvents. Some synthesized compounds demonstrated antimicrobial activity.
The present invention relates to novel heterocyclic compounds and to their use in the treatment of various disease states, including cardiovascular diseases and diabetes. In particular embodiments, the structure of the compounds is given by Formula (I):
wherein Q1, Q2, R2, R3, R4, R5, and R6 are as described herein.
The invention also relates to methods for the preparation of the compounds, and to pharmaceutical compositions containing such compounds.
