We report herein the enantioselective Cu-catalyzed conjugate addition of organometallic reagents to sensitive Michael acceptors and their application to the synthesis of relevant target molecules. This is one of the most important methodologies to form a C-C bond in an enantioselective manner. A wide range of alpha,beta-unsaturated aldehydes and beta,gamma-unsaturated-alpha-ketoesters has been successfully
我们在此报告有机金属试剂对敏感迈克尔受体的对映选择性铜催化的共轭加成反应及其在相关靶分子合成中的应用。这是以对映选择性的方式形成CC键的最重要方法之一。已经成功地使用了多种α,β-不饱和醛和β,γ-不饱和α-酮酸酯。反应性,区域选择性和对映选择性强烈依赖于反应条件,因此获得了中度到非常好的结果。此外,将γ-取代的α-酮酸酯用作手性结构单元,可在完全保留手性信息的情况下进一步衍生化以获得关键化合物。
