A convenient preparation of 7-bromo-2H-1,4-benzothiazine-3,5,8(4H)-trione and its application in the synthesis of the conaquinone B skeleton
Abstract
7-Bromo-2H-1,4-benzothiazine-3,5,8(4H)-trione was synthesized by reaction of 5-bromo-2-nitro-1,4-benzoquinone with methyl thioglycolate followed by reductive cyclization and oxidation. The Diels-Alder reaction of the product quinone with myrcene afforded the expected naphthothiazine. © Georg Thieme Verlag Stuttgart.
