Metal-free benzannulation of yne-allenone esters for atom-economic synthesis of functionalized 1-naphthols

A new metal-free benzannulation reaction of yne-allenone esters with H2O by using HOAc as a Lewis acid promoter is reported, providing an atom-economic protocol toward aroyl 1-naphthols with good to excellent yields. Exchanging H2O for aromatic amines resulted in iminated Z-1-naphthols with high stereoselect
