Chemistry on Benzopentathiepin. Reactios of Benzopentathiepin with Aromatic Compounds in the Presence of Lewis Acid

Abstract

Benzopentathiepin (BPT) reacted with many aromatic compounds such as benzene, l,4-dimethylbenzene, and naphthalene in the presence of Lewis acid to give various thianthrenes in moderate yields.BPT was found to serve as a 1,4-dication synthon.Recently, much attention has been paid an the chemistry of cyclic polysulfides such as lenthionine and sporidesmin in the viewpoint of biological activity. 1Especially, current interests have been centered on synthesis and reaction of
