资源简介：
A Rh(III)-catalyzed
annulation between salicylaldehydes and diazo
compounds with controllable chemoselectivity is described. AgNTf2 favored benzofurans via a tandem C–H activation/decarbonylation/annulation
process, while AcOH led to chromones through a C–H activation/annulation
pathway. The reaction exhibited good functional group tolerance and
scalability. Moreover, only a single regioisomer of benzofuran was
obtained due to the in situ decarbonylation orientation effect.
