A three-layer chirality relay model is proposed for Rh(I)-mediated enantioselective siletane activation. A chiral ligand in the back layer controls the position of the alkyne-coordinated metal center in the middle layer, which then provides a chiral environment for the incoming substrate at the front layer. A two-dimensional contour map analysis further clarified this model.
针对铑(I)介导的对映选择性硅杂环丁烷活化,提出了一种三层手性传递模型。后层中的手性配体控制中层炔烃配位金属中心的位置,进而为前层中进入的底物提供手性环境。二维等高线图分析进一步阐明了该模型。
