Asymmetric conjugate addition to prochiral cycloalkenones was examined by utilizing a zinc azaenolate as well as a copper one derived from an acetone imine of optically active erythro-2-methoxy-1,2-diphenylethylamine, the best enantioselectivity of the resulting 3-acetonylcycloalkanones being as high as 92% ee.
通过使用氮杂锌酸锌和衍生自旋光性赤-2-甲氧基-1,2-二苯乙胺的丙酮亚胺的铜基铜,检查了前手性环烯酮的不对称共轭加成反应,所得3-丙酮基环链烷酮的最佳对映选择性为:高达92%ee。
