Acylated benzothiazinesulfoneamides: Synthesis and molecular structure

Abstract

1,2,3,4,4a,10b-Hexahydro-1,4-methano-6H-dibenzo[c,e]-5,6-thiazine-5,5-dioxide has been converted into the corresponding N-acyl derivatives via the reaction with acid chlorides and anhydrides. X-Ray diffraction data have revealed the presence of an intramolecular С–H···O=S hydrogen bond in the molecules of the obtained compounds.
