An enantioselective Michael addition of ketones to nitroolefins has been accomplished using a novel chiral amino-naphthalene-derived prolinamides catalyst 1. The desired Michael adducts were obtained in high yields (up to 93%) as well as good diastereoselectivities (>99:1) and enantioselectivities (48%-99% ee).
使用新型手性氨基萘衍生的脯氨酰胺催化剂 1 实现了酮与硝基烯烃的对映选择性迈克尔加成。 以高产率(高达 93%)和良好的非对映选择性(>99:1)获得了所需的迈克尔加合物和对映选择性 (48%-99% ee)。
