In this protocol, we report a Mo-catalyzed anti-dihydroxylation of secondary allylic alcohols, providing a general method for the preparation of 1,2,3-triols bearing up to three continuous stereocenters with excellent diastereocontrol. The mechanistic studies reveal that this dihydroxylation reaction consists of two steps and up to excellent diastereomeric ratios of the final triol products can be
在该协议中,我们报告了钼催化的仲烯丙基醇的抗二羟基化作用,为制备具有多达三个连续立体中心的1,2,3-三醇提供了出色的非对映异构控制的一般方法。机理研究表明,该二羟基化反应包括两个步骤,并且由于初始环氧化中的非对映控制和随后的原位水解中的区域控制都很高,因此最终三醇产物的非对映异构体比例可以达到极高的水平。
