报道了氧化还原中性条件下过渡金属铑催化氧化锍叶立德C—H键活化与两类环状重氮化合物发生环化反应, 分别合成结构多样性的稠环和螺环. 该反应通过螯合辅助的C—H活化、卡宾插入及随后的分子内[3+3]环化或者[4+1]螺环化反应进行.

The Rh(III)-catalyzed C—H functionalization of sulfoxonium ylides and successively annulation with two classes of cyclic diazo compounds has been realized, affording structurally diverse fused-ring or spirocyclic compounds under redox- neutral conditions. The reaction proceeds via successive chelation-assisted C—H activation, carbene insertion, and intra- molecular [3 + 3]/[4 + 1] annulation processes.

Key words: rhodium catalysis, sulfoxonium ylide, C—H activation, diazo compound, annulation
