class of chiral spirosilabiindane scaffolds by Rh-catalyzed asymmetric double hydrosilation, for the first time. Enantiopure SPSiOL (spirosilabiindane diol), a new type of chiral building block for the preparation of various chiral ligands and catalysts, was readily prepared on greater than 10 gram scale using this protocol. The potential of this new spirosilabiindane scaffold in asymmetric catalysis
本文首次报道了通过Rh催化的不对称双氢硅化反应开发的一类手性螺硅双茚满骨架。Enantiopure SPSiOL(螺硅双茚满二醇)是一种用于制备各种手性配体和催化剂的新型手性结构单元,使用该方案可以轻松地以大于10克的规模制备。通过开发相应的单齿亚磷酰胺配体(SPSiPhos),初步证明了这种新型螺硅双茚满骨架在不对称催化中的潜力,该配体既可用于Rh催化的加氢反应,又可用于Pd催化的分子内碳胺化反应。
