Rh(III)-catalyzed synthesis of mesoionic heterocycles has been achieved via C–H activation of sydnones and oxidative coupling with internal alkynes. This reaction occurred under mild conditions with high efficiency, broad substrate scope, and low catalyst loading. Moreover, synthetic applications of a coupled product have been demonstrated in the late-stage derivatization into a variety of highly functionalized
Rh(III)催化的中性离子杂环的合成是通过Synonnon的C–H活化和与内部炔烃的氧化偶联而实现的。该反应在温和的条件下以高效率,较宽的底物范围和较低的催化剂负载量进行。此外,已在后期衍生化为各种高度功能化的支架中证明了偶联产物的合成应用。
