As in Reaction Scheme 2, lithium-halogen exchange of compound (76), followed by addition of the resulting nascent lithiated aromatic to perbenzylated gluconolactone (2), produces a mixture of the corresponding lactols, which is reduced using triethylsilane and boron trifluoride etherate. Subsequent desilylation using tetrabutylammonium fluoride (TBAF) affords 1-naphthalenemethanol (77) in a reasonable yield for the three steps.
