enantio‐ and diastereoselective copper‐catalyzed three‐component coupling of 1,3‐dienes, bis(pinacolato)diboron, and acylsilanes is reported. The reaction proceeds well with different 1,3‐dienes and a broad range of aryl‐ as well as alkenyl‐ but also alkyl‐substituted acylsilanes. The target compounds are formed with high regio‐, diastereo‐, and enantioselectivity (up to 99 % ee and d.r. >20:1) and are
据报道,通过对映和非对映选择性铜催化的1,3-二烯,双(频哪醇)二硼和酰基硅烷的三组分偶联,可以有效合成功能化的叔α-硅醇。使用不同的1,3-二烯和各种芳基以及链烯基以及烷基取代的酰基硅烷,反应可以很好地进行。目标化合物具有很高的区域,非对映和对映选择性(高达99%ee和dr> 20:1),是高度通用的合成构件。
