Synthesis of ammonium 5-arylcarbamoyl-4-heteryl-6-methyl-3-cyano-1,4- dihydropyridine-2-thiolates and 4-heteryl-5-carbamoyl-6-methyl-3-cyano-1,4- dihydropyridine-2-selenolates

The condensation of enamines derived from acetoacetanilides, heterocyclic aldehydes, and cyanothioacetamide yielded ammonium 5-arylcarbamoyl-5-heteryl-6- methyl-3-cyano-1,4-dihydropyridine-2-thiolates, which were subsequently used for the synthesis of substituted 2-alkylthio-1,4-dihydropyridines, 2-alkylthiopyridines, and thieno[2,3-b]pyridines. The reaction of acetoacetamide with heteroaromatic aldehydes and cyanoselenoacetamide in the presence of N-ethylmorpholine yielded N-ethylmorpholinium 4-heteryl-5-carbamoyl-6-methyl-3- cyano-1,4-dihydrolyridine-2-selenolates, from which substituted 2-alkylseleno-1,4-dihydropyridines were prepared. 2005 Pleiades Publishing, Inc.
