Abstract: This study details an aluminum‐catalyzed regioselective isomerization of 2,2‐disubstituted oxetanes to yield homoallylic alcohols. The reaction takes place in toluene at 40 ºC, employing 1 mol % of Al(C6F5)3 as catalyst. This catalytic system shows a wide substrate scope (12 examples). The optimized conditions are especially useful for electron‐rich aryl oxetanes, completely suppressing the formation of allyl isomers and reducing the amount of the dimer by‐product. The synthetic applicability of the reported m… Show more
