Abstract

An efficient synthesis of benzothiazines from (o-halophenyl)methylamine has been achieved. This novel one-pot procedure involves CuI catalyzed C-S bond formation using dithioesters followed by a heterocyclization reaction. This efficient protocol has the advantages of one-pot synthesis, short reaction time, good yields (60-78%) and operational simplicity.
