methoxymethyl protecting group, with 7‐endo‐trig alkoxycyclization then dominating instead (see scheme). In addition, the regioselectivity of the La‐catalyzed cycloetherification can be modulated (5‐exo versus 6‐endo versus 7‐endo) simply through subtle variation in the functionalization of the allene component.
