A kinetic resolution of hindered Morita-Baylis-Hillman adducts has been successfully achieved in excellent selectivities via Rh(I)-catalyzed asymmetric 1,4-addition/β-hydroxyelimination with the use of a chiral sulfinamide/olefin hybrid ligand. This study provides a novel and efficient access to both optically active hindered highly functionalized alkenes and Morita-Baylis-Hillman adducts.
通过使用手性亚砜/烯烃混合配体，通过 Rh(I)-催化的不对称 1,4-加成/β-羟基消除反应，成功地实现了受阻的 Morita-Baylis-Hillman 加合物的动力学拆分，并获得了优异的选择性。该研究为具有光学活性的受阻高官能化烯烃和 Morita-Baylis-Hillman 加合物的合成提供了一种新颖而有效的方法。
