Reaction of 1-Nitro-2, 2'-bismethylthioethylene. III. Reaction of Methyl 1-Cyano-2-methylthio-3-nitrocrotonate with Hydrochloric Acid

Abstract

Methyl 1-cyano-2-methylthio-3-nitrocrotonate was reacted with hydrochloric acid under various conditions and 2, 5-dihydro-2-hydroximino-5-imino-4-methoxycarbonyl-3-methylthiofuran monohydrochloride, 2, 5-dihydro-2-hydroximino-4-methoxycarbonyl-3-methylthiofuran, and α-methylthio-β-methoxycarbonylmaleic anhydride were synthesized. The mutual relationship of these products was clarified.
