blocks with active methylene catalyzed by iodine were investigated in a multicomponentone-pot protocol. A series of 5,7-diaryl-4,7-dihydrotetrazolo[1,5-a]pyrimidines C and 5-methyl-7-aryl-4,7-dihydrotetrazolo[1,5-a]pyrimidine-6-carboxylates D were obtained in moderate to good yields. Further exploration rapidly afforded various E in good to excellent yields; in addition, compound F was also obtained under
