25-Hydroxyvitamin D2 as synthesized conveniently and stereoselectively for the first time by utilizing Sharpless' chiral epoxidation and the subsequent regio- and stereoselective methylation with lithium dimethylcuprate to introduce the desired chirality at C(24) and the reductive elimination of the vicinal hydroxy sulfone to introduce stereoselectively the E double bond at C(22) of the target molecule
25-羟基维生素D 2的合成是首次并通过Sharpless的手性环氧化和随后的区域选择性和立体选择性的甲基化与二甲基铜酸锂进行立体选择性合成,从而在C(24)处引入所需的手性,并还原消除了邻位羟基砜以立体选择性地在目标分子的C(22)处引入E双键。
