the first highly enantioselective Rh-catalyzed carboacylation of olefins via C-C bond activation of benzocyclobutenones. Good yields and excellent enantioselectivities (92-99% ee, 14 examples) were obtained for substrates with various steric and electronic properties. In addition, fully saturated poly-fused rings were prepared from the carboacylation products through a challenging catalytic reductive
在这里,我们报告了第一个通过苯并环丁烯酮的 CC 键活化对烯烃进行高度对映选择性的 Rh 催化碳酰化。对于具有各种空间和电子特性的基材,获得了良好的产率和出色的对映选择性(92-99% ee,14 个实例)。此外,通过具有挑战性的催化还原脱芳构化方法,由碳酰化产物制备了完全饱和的聚稠环。这些研究提供了一种独特的方法来制备手性碳骨架,这些骨架是用传统方法难以获得的。
