The first asymmetric Michael addition of 3-substituted phthalides to nitroolefins promoted by amino acid-incorporating multifunctional catalysts has been developed. The reported method led to the synthesis of 3,3-disubstituted phthalide derivatives in high yields, and in a highly diastereoselective and enantioselective manner. Facile synthesis of a chiral bicyclic lactam has also been demonstrated
已经开发了通过结合氨基酸的多功能催化剂促进的3-取代的邻苯二甲酸酯到硝基烯烃的第一次不对称迈克尔加成反应。报道的方法导致高产率,高非对映选择性和对映选择性的方式合成3,3-二取代的邻苯二甲酰胺衍生物。还已经证明容易合成手性双环内酰胺。
