Ring Transformations of 4-Aryl-3-haloacylthio-3-isothiazoline-5-thiones as a New Access to the 4(5H)-Thiazolone and 5,6-Dihydro-4H-1,3-thiazin-4-one Rings

The reactions of 4-aryl-3-haloacylthio-3-isothiazoline-5-thiones with reactive acetylenes (e.g. dimethyl acetylenedicarboxylate and dibenzoylacetylene) afford 2-[1,3-dithiol-2-ylidene(aryl)methyl]-4(5H)-thiazolones and 5,6-dihydro-2-[1,3-dithiol-2-ylidene(aryl)methyl]-4H-1,3-thiazin-4-ones mostly in high yields.
