A general synthetic strategy was designed for the preparation of 7‐substituted‐4‐methoxy‐ and 4‐hydroxyspiro[benzofuran‐2(3 H )‐cyclohexanes] 5 and 6 (Figure 1) using successive, regioselective hetero‐atom‐facilitated aromatic lithiation reactions and subsequent reaction with various electrophiles.
