rhodium-catalyzed 3-component conjunctive diastereo- and regioselective arylamidation of (homo)allylic sulfides, organon boronic acids, and dioxazolones is reported. These reactions deliver the 1,2-insertion and 2,1-insertion arylamidation products, respectively, for allylic sulfides and homoallylic sulfides. The enantioselective arylamidation of terminal and internal allylic sulfides is achieved, furnishing
报道了(同)烯丙基硫化物、有机硼酸和二恶唑酮的铑催化三组分联合非对映和区域选择性芳基酰胺化。这些反应分别产生烯丙基硫化物和高烯丙基硫化物的 1,2-插入和 2,1-插入芳基酰胺化产物。实现了末端和内部烯丙基硫化物的对映选择性芳基酰胺化,以高产率和高非对映选择性和对映选择性提供具有一个或两个连续立构中心的各种1,3- N,S化合物。机理研究表明,由天然且易于去除的硫化物基团引起的周转限制和选择性决定步骤发生了变化。
