synthesis and selected reactions of 2-amino-3-(cyanomethylsulfonyl)thiophene is reported. In particular, cyclization reaction of the versatile aminothiophene yielded a number of novel thieno[3,2-b][1,4]-thiazine 1,1-dioxides, as well as the analogous thieno[2,3-e][1,3,4]thiadiazine 4,4-dioxide. Reaction of the thienothiazine system with hydrazine was subsequently explored, which resulted in either ring-opening
