polyrimetric kinetic study, of the epimerisation of optically pure spirophosphoranes derived from α-aminoalcohols or α-aminoacids, leads to mechanistic conclusions. Evidence from isotopic, solvent and concentration effects and values of the activation parameters are consistent with a regular epimerisation mechanism in these spirophosphoranes involving the intramolecular stereolability of these molecules
对源自α-氨基醇或α-氨基酸的光学纯螺环磷酰胺进行差向异构化的多尺度动力学研究得出了机械学结论。来自同位素,溶剂和浓度效应以及活化参数值的证据与这些螺磷光烷中涉及这些分子的分子内立体性的常规差向异构机制是一致的。
