Abstract

Michael addition of imidazole (1) and benzimidazole (5) to alkyl propiolate (2) can be promoted by K10 montmorillonite clay affording alkyl 3-(imidazol-1-yl)acrylate (3) and alkyl 3-(benzimidazol-1-yl)acrylates (6), respectively. Michael adduct of 2-mercaptobenzimidazole (8) undergoes cyclization in the presence of clay catalyst to 4-oxo-4H-[1,3]thiazino[3,2-a]benzimidazole (9).
