αα′-Dicyano-(1,3-dithiacyclobutane-2,4-diylidene)diacetamides (desaurins) from thiazine derivatives

Abstract

The title compounds (1) were synthesized in good yields by refluxing N-alkyl-2-cyano-3-mercapto-3-methylthio-acrylamides (3) with acetic anhydride. Compounds (3) were prepared by a novel hydrogenolysis of 2,2-disubstituted 3,4-dihydro-6-methylthio-4-oxo-2H-1,3-thiazine-5-carbonitriles (2) with lithium aluminium hydride or sodium borohydride.
