Addition of P–H species to carbonyl groups, namely the Pudovik reaction, normally delivers hydroxyl phosphorus compounds, along with phosphate byproducts in some cases. A few controllable systems starting from phosphites were set up to mainly provide the phosphates. Herein, we present a highly selective protocol starting from phosphonate precursors leading to phosphinate derivatives. Enantioenriched phosphinates
在羰基上添加P–H物种,即Pudovik反应,通常会释放羟基磷化合物以及某些情况下的磷酸盐副产物。建立了一些从亚磷酸盐开始的可控系统,主要提供磷酸盐。在本文中,我们提出了从膦酸酯前体到次膦酸酯衍生物的高选择性方案。从手性氧化膦前体成功获得了对映体富集的次膦酸酯。进行了实验和理论研究以了解机械细节。
