both enantiomers of a variety of trialkyl phosphates with enantiomeric excesses ranging from 87 to 92% is described. Bis(2,4-dichlorophenyl) phosphoramidates bearing a 2-substituted pyrrolidine moiety as the chiral auxiliary are prepared and examined for their stereoselectivity. Considerations based on both the absolute configuration of the product phosphates as well as the X-ray structural determination
描述了制备各种磷酸三烷基酯的两种对映异构体的通用方法,其中对映异构体过量范围为 87% 至 92%。制备带有 2-取代吡咯烷部分作为手性助剂的双 (2,4-二氯苯基) 氨基磷酸酯并检查它们的立体选择性。基于产物磷酸盐的绝对构型以及双(2,4-二氯苯基)氨基磷酸酯之一的 X 射线结构测定的考虑表明,这些取代发生在磷的构型发生显着反转的情况下
