Practical catalytic cross-coupling of secondary alkyl electrophiles with secondary alkyl nucleophiles under Cu catalysis has been realized. The use of TMEDA and LiOMe is critical for the success of the reaction. This cross-coupling reaction occurs via an S(N)2 mechanism with inversion of configuration and therefore provides a general approach for the stereocontrolled formation of C-C bonds between
已经实现了在铜催化下仲烷基亲电试剂与仲烷基亲核试剂的实际催化交叉偶联。TMEDA 和 LiOMe 的使用对于反应的成功至关重要。这种交叉偶联反应通过构型反转的 S(N)2 机制发生,因此为手性仲醇的两个叔碳之间立体控制形成 CC 键提供了通用方法。
