It was shown that 2-(1,3-thiazolidin-2-ylidene)acetamides can be used as 2-enamides in cyclocondensation reactions with oxalyl chloride, leading to the formation of new heterocyclic assemblies – 4-(4-oxo-1,3-thiazolidin-2-ylidene)pyrrolidine-2,3,5-triones in 50–88% yields.
结果表明,在与草酰氯的环缩合反应中,2-(1,3-噻唑烷-2-亚甲基)乙酰胺可用作2-酰胺,导致形成新的杂环组装体– 4-(4-oxo-1, 3-噻唑烷-2--2-亚基)吡咯烷-2,3,5-三酮的产率为50-88%。
