For the first time, nucleophilic ring-openings of cyclopropanated 7-oxabenzonorbornadiene were investigated, providing a novel approach to the preparation of 2-methyl-1,2-dihydronaphthalen-1-ols. Satisfactory yields (up to 95%) were achieved using n-Bu2CuCNLi2 as the nucleophile and Et2O as the solvent. The reaction demonstrated successful incorporation of primary, secondary, tertiary and aromatic
