Tandem ring‐closing enyne metathesis (RCEM)/ring‐closing olefin metathesis (RCM) of tetraenynes with Grubbs second‐generation catalyst, followed by elimination, was found to be a new and efficient synthetic approach to biaryl compounds. A preliminary asymmetric version of this approach, which used homochiral Ru–alkylidene catalysts, is also presented.
发现使用Grubbs第二代催化剂将四烯炔的串联闭环烯复分解(RCEM)/闭环烯复分解(RCM),然后消除,是一种新的有效的联芳基化合物合成方法。还介绍了这种方法的初步不对称形式,它使用了手性钌-亚烷基催化剂。
