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.
