Abstract

The synthesis and selected reactions of the versatile heterocycle 2‐amino‐3‐cyanomethylsulfonyl‐4,5‐dimethylfuran is reported. In particular, cyclization reaction of the aminofuran yielded a number of novel furo[3,2‐b]thiazine 1,1‐dioxides. Additionally, a novel tetracyclic system, namely a pyrrolo[2′,3′:5,6]‐[1,4]thiazino[3,2‐b]quinoline 4,4‐dioxide, is prepared via an intramolecular triple‐cyclization in which the furan ring is opened and reclosed as a pyrrole.
