✦ Synopsis

Abstract

Reaction of 1,5‐benzothiazepines 3, obtained from chalcones 2 and o‐aminobenzenthiol, with the (phenylhydrazino) chloromethylenecarboxylates 4 in the presence of Et~3~N leads to a series of new [1,2,4]triazolo[5,4‐d][1,5]benzothiazepine derivatives 5. Their structures were established using spectroscopic methods and that of compound 5d was confirmed using X‐ray diffraction analysis. J. Heterocyclic Chem., (2011).

## Abstract The reaction of N‐aryl‐C‐ethoxycarbonyl nitrilimines with [1,2,4]triazepin‐3,5‐dithione leads to title compounds. The 1,3‐dipolar cycloaddition is completely peri and regioselective. The preferred orientation of addition is predicted correctly by AM~1~ calculation.
