Methods have been developed for the N-alkylation of 1,2,4-dithiazolidine-3,5-dione 2 and the subsequent conversion of the N-alkylated derivatives into isocyanates 5. An extension of this methodology onto a solid-support is also reported. X-ray crystallographic analysis has been carried out on potassium 1,2,4-dithiazolidine-3,5-dione 3 for structural comparison with the parent heterocycle 2.
已经开发出1,2,4-二噁唑烷-3,5-二酮 2 的N-烷基化方法,以及将N-烷基化衍生物转化为异氰酸酯 5 的后续过程。还报告了该方法在固相上的扩展。对钾盐1,2,4-二噁唑烷-3,5-二酮 3进行了X射线晶体学分析,以与母体杂环化合物 2 进行结构比较。
