A flexible route for the stereoselective synthesis of trisubstituted γ-butyrolactones, namely (+)-blastomycinone and its analogs, is devised by the Sharpless asymmetric epoxidation and the regioselective ring opening reaction with dibutylcopper lithium as the key steps to introduce the requisite alkyl chain.
通过 Sharpless 不对称环氧化和与二丁基铜锂的区域选择性开环反应作为引入所需烷基链的关键步骤,设计了一种灵活的立体选择性合成三取代 γ-丁内酯(即 (+)-blastomycinone 及其类似物)的路线。
