Synthesis of 4H-1,4-Benzothiazines via Lithiation Alpha to Sulphur of 2-Acylaminophenyl Alkyl Sulphides, Sulphoxides, and Sulphones
4H-1,4-Benzothiazines, their monoxides, and their dioxides are readily prepared via lithiation and intramolecular cyclisation of 2-acylaminophenyl alkyl sulphides, sulphoxides, and sulphones with lithium di-isopropylamide in tetrahydrofuran at -50 deg C.
