The salt of a sulfonated succinic acid is cyclized, then converted to novel sulfonated hydroxamic acids by reaction with hydroxylamine (which is added or formed in situ), and the novel hydroxamic acid is then cyclized to the sulfo-N-hydroxysuccinimide salt. This synthetic procedure is simple, direct, and more rapid than present procedures for synthesis of the succinimide. Novel sulfo-hydroxamic acid intermediates are formed during this procedure.
磺化
琥珀酸的盐被环化,然后通过与
羟胺反应(添加或原位形成)转化为新的磺化羟
肟酸,然后将新的羟
肟酸环化为磺酰-N-羟基琥珀
酰亚胺盐。这种合成方法简单、直接,比目前合成琥珀
酰亚胺的方法更快。在此过程中形成了新的磺化羟
肟酸中间体。
