用ＭＮＤＯ半经验分子轨道计算方法对Ｎ－磷酰丙氨酸生成的五配位磷中间体的假旋 转异构体的结构和性质进行了研究。结果表明这些异构体是高活性的，并且具有不同的反应 性质，因此他们可能成为具有多重反应性的合成子．
The structure and properties of the pseudo-rotamers of the pentacoordinated phosphorus intermediate formed by N-phosphorylalanine were studied by MNDO semi-empirical molecular orbital calculation. The results show that these isomers are highly active and have different reactivity properties, so they may become multi-reactive synthons.
