A series of tetrazoles linked to the butenolide core via benzene rings were prepared by the Stille coupling reaction of α-(tributylstannyl)butenolides and 5-(alkylsulfanyl)-1-(4-iodophenyl)tetrazoles, and the compounds were tested for antifungal and cytostatic activity. Interesting antifungal activities against the filamentous strain Absidia corymbifera, and cytostatic activities against leukemic cells HL-60 and CCRF-CEM were found. The cytostatic activity requires the presence of both the butenolide ring and the alkylsulfanyl group bound to tetrazole ring. In addition, the feasibility of Pd-coupling reactions with 5-iodotetrazoles was evaluated.
