asymmetric conjugate addition a number of chiral cyclic enones are available with high ee. Here we report the sequential conjugate addition to these enones as a route towards multisubstituted chiral cyclic ketones. A subsequent Baeyer—Villiger oxidation followed by ring-opening results in various linear synthons containing multiple stereocenters. This procedure represents a short, catalytic, and highly enantioselective
通过铜-亚磷酰胺催化的不对称共轭物的加成,可获得许多具有高ee的手性环状烯酮。在这里,我们报告了这些烯酮的顺序共轭加成,作为迈向多取代手性环酮的途径。随后的Baeyer-Villiger氧化和开环导致包含多个立体中心的各种线性合成子。该方法代表了通往各种无环手性结构单元的短的,催化的和高度对映选择性的途径。
