A variety of important multiarylated benzenes were efficiently synthesized from phloroglucinol derivatives 1 through sequential cross-couplings via Pd-catalyzed C-OTs, Ni-catalyzed C-OC(O)NEt2, and C-OMe bond activation. High selectivity was achieved based on the rational design and inherent diversity in the reactivity of different C-O bonds.
