Abstract

A solid-phase methodology to construct aminobenzimidazole tethered sultams and benzothiazepinones from commercial amino acids, amines, carboxylic acids, and sulfonyl chlorides is described. Coupling of Fmoc-Cys(Trt)-OH to resin-bound aminobenzimidazole scaffold provided an essential precursor for the construction of a variety of seven membered benzofused cyclic sulfonamides and thiazepinones via palladium catalyzed Buchwald-Hartwig type intramolecular cyclization.
