One-pot synthesis of trans-7-aryl-6H-6a,7-dihydro[1]benzopyrano[3,4-c][1,5]benzothiazepines

Green chemical approaches for the condensation reaction of benzenethiols and 3-arylidenenchroman-4-ones as synthons for the synthesis of a series of newtrans-7-aryl-6H-6a,7-dihydro[1]benzo pyrano[3,4-c][1,5]benzothiazepines which may possess potential biological activity are described.{A figure is presented}.

Oxazepines and Thiazepines. XIII - Conformational Analysis of 2,3-Dihydrobenzothiazepine Derivatives

The conformation and relative configuration of various condensed heterocycles possessing a 2,3-dihydro-1,5-benzothiazepine moiety and their synthetic intermediates were determined by 1H and 13C NMR spectroscopy.It was found that epimerization takes place during the ring closure reaction.
