title: Approach to construct polysubstituted 1,2-dihydronaphtho[2,1-b]furans and their aerobic oxidative aromatization.
abstract: Triarylaminium salt was disclosed as an efficient initiator for the novel Friedel-Crafts alkylation/annulation cascade reaction between chalcone epoxides and 2-naphthols to construct polysubstituted 1,2-dihydronaphtho[2,1-b]furans. The DDQ/NaNO(2)/O(2) catalytic system was first applied to the aerobic oxidative aromatization of heterocycles, and a simple and efficient one-pot tandem FC alkylation/annulation/aerobic oxidative aromatization procedure was also developed for the synthesis of complex naphtho[2,1-b]furans.
