Pick one out of three: Acyclic and cyclic 1,2,3‐triols are silylated with exceptional site‐ and enantioselectivity by a small‐molecule catalyst to afford silyl ethers having a neighboring diol moiety. The new process is applied to the enantioselective total syntheses of three cleroindicins, natural products isolated from a plant used in China to battle malaria and rheumatism.
从三个中选择一个:无环和环状 1,2,3-三醇被小分子催化剂以优异的位点和对映选择性甲硅烷基化,得到具有相邻二醇部分的甲硅烷基醚。新工艺应用于三种 cleroindicins 的对映选择性全合成,这是一种从中国用于对抗疟疾和风湿病的植物中分离出来的天然产物。
