α,β-Epoxy esters were rapidly reduced at room temperature to yield β-hydroxy esters with retention of the configurations at the β-carbon atoms by using SmI2-THF-HMPA system in the presence of N,N-dimethylaminoethanol (DMAE). The conditions were successfully applied to the synthesis of vinylogous δ-hydroxy esters.
在存在N,N-二甲基氨基乙醇(DMAE)的情况下,使用SmI 2 -THF-HMPA系统在室温下将α,β-环氧酯迅速还原,生成具有保留在β-碳原子上构型的β-羟基酯。该条件已成功地应用于乙烯基δ-羟基酯的合成。
