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
报道了2-氨基-3-(氰基甲基磺酰基)噻吩的合成和选择的反应。特别是,通用氨基噻吩的环化反应产生了许多新型的噻吩并[3,2- b ] [1,4]-噻嗪1,1-二氧化物,以及类似的噻吩并[2,3- e ] [1 ,3,4]噻二嗪4,4-二氧化物。随后研究了噻吩噻嗪系统与肼的反应,这导致噻嗪开环并形成氨基吡唑或取决于噻嗪取代基的单独开环。另外,描述了双(2-氨基-3-噻吩基)砜和相应的双乙酰胺的合成。
