The reaction of 3-(benzothiazol-2-yl)-3oxopropanenitrile 1 with active methylene reagents 2a-d and sulfur afforded polysubstituted thiophenes 3a-c . The synthetic potential of the b-enaminonitrile moiety in 3a was explored. The reaction of 3a with active methylene reagents 2a-e afforded thieno [2,3b
