Syntheses of 2,4-diaryl-2,3-dihydro-1,5-benzothiazepines

Abstract

The condensation of α,β-unsaturated ketones with substituted o-aminothiophenols, obtained by reductive cleavage of the corresponding disulfides in the presence of triphenylphosphine, is an effective method for the synthesis of 2,4-diaryl-2,3-dihydro-1,5-benzothiazepines under neutral conditions.
