Chiral phosphorous acid diamides were prepared by condensation of N,N′-disubstituted C2 diamines with PCl3 followed by an equivalent of water. Deprotonation of these acids with n-butyl lithium or LDA gave the lithium salt which reacted smoothly with alkyl halides to give the substituted phosphonamides in good yield.
通过将N,N'-二取代的C 2二胺与PCl 3缩合,然后再加入等价的水来制备手性亚磷酸二酰胺。这些酸用正丁基锂或LDA脱质子化得到的锂盐与烷基卤化物平稳反应,以高收率得到取代的膦酰胺。
