The cyanothioacetanilide derivative 3 reacted readily with either α-halocarbonyl compounds 4 or α-halodicarbonyl compounds 8 to afford the same thiophene derivatives 6. Compound 3 also reacted with hydrazonoyl chlorides 12 and 16 and furnished the new polyheterocyles 14 and 17, respectively. © 2002 Wiley Periodicals, Inc.
