novel multifunctional chiral aminophosphine catalysts were developed through a concise synthetic strategy from easily available starting materials. The highly enantioselective intermolecular cross Rauhut-Currier reactions of vinyl ketones with 3-acyl acrylates and 2-ene-1,4-diones catalyzed by (S,S)-5a were well realized, generating a wide range of the structurally important chiral multicarbonyl products
一系列结构新颖的多功能手性氨基膦催化剂是通过简单的合成策略从容易获得的起始材料中开发出来的。( S , S )-5a催化的乙烯基酮与 3-酰基丙烯酸酯和 2-ene-1,4-二酮的高度对映选择性分子间交叉 Rauhut-Currier 反应得到了很好的实现,产生了结构上重要的手性多羰基化合物具有高立体控制(高达 97% 的产率,99% ee)的产品。此外,还进行了一系列31 P NMR 实验以进一步研究催化过程。
