derivative (1). Hydration of the internal alkyne in the coupled products and stereoselective reduction of the resulting ketone intermediate provides a general approach to a library of stereoisomeric 1, 3, 5, ... alternating polyols (2). The strategy is demonstrated in a stereoselective synthesis of the C11-C28 polyol substructure of the natural product RK-397.
我们用于组装聚乙酸酯结构的新合成策略具有源自环氧炔醇衍生物 (1) 的任何立体异构体的六碳模块的高效交叉偶联。偶联产物中内部炔烃的水合和所得酮中间体的立体选择性还原为立体异构体 1、3、5、...交替多元醇 (2) 库提供了通用方法。该策略在天然产物 RK-397 的 C11-C28 多元醇亚结构的立体选择性合成中得到证明。
