A stereoconvergent method for the catalytic asymmetric Negishi cross-coupling of racemic secondary propargylic halides with arylzinc reagents has been developed. Neither family of compounds has previously been shown to be a suitable partner in such coupling processes. From a practical point of view, it is noteworthy that the catalyst components (NiCl2.glyme and pybox ligand 1) are commercially available
已经开发了一种立体聚合方法,用于外消旋仲炔丙基卤化物与芳基锌试剂的催化不对称 Negishi 交叉偶联。此前,这两个家族的化合物都没有被证明是此类偶联过程中的合适伙伴。从实用的角度来看,值得注意的是催化剂组分(NiCl2.glyme 和 pybox 配体 1)是可商购的。
