New, simple, sulfinamide-based branched olefin ligands have been developed and successfully used in Rh-catalyzed asymmetric arylations of cyclic ketimines, providing efficient and highly enantioselective access to valuable benzosultams and benzosulfamidates containing a stereogenic quaternary carbon center. This is the first example of applying a sulfur-olefin ligand in catalytic asymmetric addition
新的、简单的、基于亚磺酰胺的支链烯烃配体已被开发并成功用于 Rh 催化的环状酮亚胺的不对称芳基化,为获得有价值的 benzosultam 和含有立体季碳中心的苯磺酰胺提供高效和高度对映选择性的途径。这是在亚胺催化不对称加成中应用硫-烯烃配体的第一个例子。
