Abstract
Condensation of ketene dithioacetal derivatives with some aminoazoles (5-aminotetrazole monohydrate, 2-aminobenzimidazole, 2-aminobenzothiazole, and 2-aminothiazole) in the presence or absence of triethylamine gave the corresponding tetrazolopyrimidines, benzimidazopyrimidines, benzothiazolopyrimidines, and thiazolopyrimidines.
