2-cyano-3-mercapto-3-(methyl-thio)acrylamide (1) with benzoic acid in the presence of polyphosphate ester gave 5-carbomoyl-4-methylthio-2-phenyl-1,3-thiazin-6-one (5); the structures of (5) and its 2,3-dihydro-derivative (6) were determined by single-crystal X-ray diffraction.
在多磷酸酯的存在下,将2-氰基-3-巯基-3-(甲基-硫代)丙烯酰胺(1)与苯甲酸缩合,得到5-氨基甲酰基-4-甲基硫代-2-苯基-1,3-噻嗪-6一(5); 通过单晶X射线衍射确定(5)及其2,3-二氢衍生物(6)的结构。
