An efficient method for the construction of various pyrazolo[5,1-a]isoquinolines has been achieved via Ru(II)-catalyzedα-carbonylsulfoxoniumylide annulations with aryl substituted pyrazoles. This oxidant-free transformation occurred through pyrazole-directed C–H activation, Ru-carbene insertion, and acid-promoted carbonyl condensation processes, enabling dual C–C and C–N bond formation. A broad
一种有效的构建各种吡唑并[5,1- a ]异喹啉的方法是通过Ru( II )催化的α-羰基氧化鎓叶立德与芳基取代的吡唑环化。这种无氧化剂转化通过吡唑导向的 C-H 活化、Ru-卡宾插入和酸促进的羰基缩合过程发生,从而形成双 C-C 和 C-N 键。两个耦合组件的广泛底物范围以高产率有效地工作。
