A practical protocol for efficient synthesis of both PAMPO enantiomers as well as related functionalised P-stereogenic phosphine oxides in 1–3 steps from effectively resolved (S P)-l-menthyl o-anisyl­-(phenyl)phosphinylacetate has been developed. Examples of non-stereo­selective quaternisation of a tertiary phosphine by alkyl halides have been revealed.

氯乙酸1-甲基乙酸酯酯的对映体合成和经典季铵化反应中P的立体突变

两种对映异构体PAMPO的有效合成,以及在从有效解决(1-3步骤相关官能P-立体氧化膦的实际协议小号 P) --薄荷基Ö -anisyl-(苯基)phosphinylacetate已经研制成功。已经揭示了通过烷基卤对叔膦进行非立体选择性季铵化的实例。
