A simple protocol for the synthesis of α-diarylacetic esters from benzoins is described. In situ generated acetal assists rapid 1,2-aryl migration in a stereospecific manner, paving the way to make enantioenriched α-diarylacetic esters from easily accessible enantiopure benzoins.
描述了一种由苯偶姻合成α-二芳基酸酯的简单方案。原位生成的乙缩醛以立体有择的方式辅助1,2-芳基的快速迁移,为从容易获得的对映纯苯偶姻制备对映体富集的α-二芳基酸酯铺平了道路。
