Highly enantioselective Michael addition of acetone to a variety of nitroalkenes promoted by simple chiral primary amine bifunctional catalysts (e.g., Noyori's Ts-DPEN ligand) together with terephthalic acid in excellent yields (84-99 %) and enantioselectivities (93―98 % ee) is reported.
在简单的手性伯胺双功能催化剂(例如 Noyori 的 Ts-DPEN 配体)和对苯二甲酸的促进下,丙酮与各种硝基烯烃的高度对映选择性迈克尔加成反应,以优异的产率 (84-99%) 和对映选择性 (93-98% ee)被报道。
