Abstract

The reaction of 2-(trimethylsilyl)phenyl triflate with aroyl­acetones in the presence of CsF gave the corresponding 4-aryl-2-naphthols. Substituted triflates also reacted with aroylacetones to afford 4-aryl-2-naphthols regioselectively. The enantioselective oxidation of 4-aryl-2-naphthols with a chiral tridentate oxovanadium(IV) complex furnished the corresponding 4,4′-biaryl-1,1′-binaphthols in good yields.
