  ABSTRACT: (Z)-Hetarylmethylene and (Z)-substituted benzylidene derivs. of 4H-benzo[1,4]thiazine-3-thiones were prepd. by the reaction of 4H-benzo[1,4]thiazine-3-thiones with various aldehydes. Subsequent treatment of the thiazine-3-thiones with di-Me acetylenedicarboxylate and various arynes gave the corresponding di-Me 4-aryl-4,10-dihydrothiopyrano[3,2- b]benzothiazine-2,3-dicarboxylates and 12-aryl-6,12-dihydro-2,3-dimethoxy[1]benzothiopyrano[3,2-b][1,4]benzothiazines, resp.
