Chiral N-aryl sulfinamide-olefins which are readily synthesized via C-N coupling and nucleophilic substitution have been used as chiral ligands, which demonstrate moderate to excellent asymmetric catalytic performance in the rhodium-catalyzed asymmetric 1,4-addition of aryl boronic acids to cyclic enones. The chiral ligands are readily synthesized via C-N coupling reaction and nucleophilic substitution
手性 N-芳基亚磺酰胺-烯烃易于通过 CN 偶联和亲核取代合成,已被用作手性配体,在铑催化的芳基硼酸与环烯酮的不对称 1,4-加成反应中表现出中等至优异的不对称催化性能. 手性配体很容易通过 CN 偶联反应和亲核取代合成。鉴于具有 97%ee 的手性配体产生高达 95%ee 的 1,4-加成产物,N-芳基叔丁烷亚磺酰胺-烯烃配体在铑催化的不对称 1,4-加成中表现出相当高的手性诱导能力。
