reagents (whether assisted by Lis or not2') from that hemisphere about the dimer which does not enclose the bulkier groups?2 Even the poorer enantioselectivity of the Z-(CaCg) imine anionsS may be explained withoutz0 recourse to de~hela t ion ,~ because Cp substituents in cis relation to the nitrogen alkyl substituents would force the face-differentiating groups further away from the reacting C g atom
来自那个半球的关于二聚体的试剂(无论是否由 Lis 辅助 2'),该二聚体不包含更大的基团?2 即使 Z-(CaCg)亚胺阴离子的较差的对映选择性也可以在不求助于去离子的情况下解释, ~ 因为与氮烷基取代基顺式相关的 Cp 取代基会迫使表面区分基团进一步远离反应的 C g 原子。
