文摘

A rhodium-catalyzed hydroacylation of para-quinone methides (p-QMs) with salicylaldehydes has been disclosed. This method allows for the construction of α,α-diaryl-2-hydroxy acetophenones through tandem C–H activation/C–C bond formation/aromatization process. Moreover, this unprecedented hydroacylation of trisubstituted alkenes exhibits good yields with broad functional group tolerance as well as gram-scale capacity.
