CRYSTAL STRUCTURE OF SULFINAMIDES OF THE THIAZINE SERIES: FEATURES OF TRANSFERRING THE OPEN-CHAIN SUPRAMOLECULAR SYNTHON FROM THE RACEMIC TO HOMOCHIRAL ENVIRONMENT

Abstract

Abstract: The crystal structures of four representatives of sulfinamides of the thiazine series are comparatively analyzed for the occurrence of different supramolecular associates, inter- and intramolecular interactions. With a similar molecular geometry, different packing motifs occur in the crystals yielding different-type supramolecular associates due to classical N–H⋯O hydrogen bonds. The features of transferring the sulfinamide open-chain supramolecular synthon from racemic to homochiral environment consisting in the appearance of “secondary cross-linking” are studied.
