be an effective organocatalyst in the enantioselective aza-Michael addition of aromatic amines to nitroolefins giving the corresponding β-nitroamine products in good yields (65%-95%) with moderate to good enantiomeric excess (16%-70%). This study represents the first example of a chiral phosphoric acid catalyzed asymmetric aza-Michael addition reaction.
摘要 手性磷酸被发现是芳香胺与硝基烯烃的对映选择性氮杂-迈克尔加成反应的有效有机催化剂,以良好的产率 (65%-95%) 得到相应的 β-硝基胺产物,对映体过量 (16%- 70%)。这项研究代表了手性磷酸催化的不对称氮杂-迈克尔加成反应的第一个例子。
