Dihydropyridines (DHPs) with carboxamides in the 3 and 5 positions show anti-tuberculosis activity. The purpose of the present study was to synthesize new DHPs that would possibly possess anti-tuberculosis activity. So a series of N-aryl-1,4-dihydropyridine-3,5-dicarboxamides (3-38) was prepared. They were screened as antitubercular agents against one type of fast growing Mycobacterium (M. smeg...

An efficient and expeditious catalyst-free procedure was developed for the one- pot synthesis of 1, 4-dihydropyridine derivatives via the three-component reaction of various aldehydes, ethyl acetoacetate, and ammonium acetate in PEG-400. The reaction was carried out at 110°С and the products were obtained in good to high yields.
