Dearomatization of naphthols using oxy-allyl cations: efficient construction of α-all-carbon quaternary center-containing 2-(2-oxocycloalkyl)cycloalkyl diketones

Abstract

A novel strategy for the dearomatization of naphthols using in situ generated oxy-allyl cations is reported. Both α- and β-naphthols can work well in this process. Using this catalyst-free methodology, various structurally diverse α-quaternary center-containing 2-(2-oxocycloalkyl)cycloalkyl diketones can be efficiently accessed in good to excellent yields under mild conditions.
