Synthesis of fully-substituted pyridines and dihydropyridines in a highly chemoselective manner utilizing a multicomponent reaction (MCR) strategy

An efficient protocol has been developed for the synthesis of pyridines and 1,4-dihydropyridines based on chemoselective multicomponent reactions. Using readily available aldehydes, malononitrile and primary aliphatic amines, this procedure provides a divergent but straightforward access to a wide range of fully substituted pyridines and dihydropyridines via a primary amine based chemoselective strategy. Simple reaction procedure, good yields, mild reaction conditions, applicabilility to a wide range of substrates with the aid of chemoselectivity make this present protocol more innovative than existing ones.

Synthesis and pharmacological activity of some nitrofuraldehyde cyanopyridine derivatives

Compounds 3a-f were obtained by condensing 5-nitrofuraldehyde hydrazone with five iminoethers derived from the 6-alkoxy-(or alkylamino-)2-amino-4-aryl-3,5-dicyanopyridines. Tests of their antimicrobial activity against 16 micro-organisms showed that 3a (R
