The development of cyclic, six membered enol phosphonamidates utilizing the ring-closing metathesis (RCM) reaction is discussed. Phosphonamidic monochloridates are generated and further functionalized to an array of acyclic, enol phosphonamidates. Subsequent metathesis affords both desired RCM product and corresponding cross metathesis (CM) dimer. Efforts to optimize formation of desired RCM product
讨论了利用闭环复分解(RCM)反应开发环状六元烯醇式磷酸亚胺酯的方法。生成磷酰胺基一氯化物,并将其进一步官能化为一系列无环烯醇式磷酰胺盐。随后的复分解提供所需的RCM产物和相应的交叉复分解(CM)二聚体。讨论了在使CM产品最小化的同时,优化所需RCM产品形成的努力,其中有趣的空间和电子因素决定了反应模式。此策略允许生成环状烯醇式磷酸亚酰胺盐,最终应用于抗癌药环磷酰胺的C(6)取代类似物。
