摘要:
By condensation of aromatic aldehydes with cyanothioacetamide and enamines of 1,3-dicarbonyl compounds functionally substituted morpholinium 1,4-dihydropyridine-2-thiolates were obtained applied to the synthesis of 2-alkylsulfanyl-1,4-dihydropyridines, 1,4-dillydrothieno[2,3-b]-pyridines, and 2,3,4,7-tetra-hydrothiazolo[3,2-a]pyridine.
