In the presence of acid, 2-alkyl-2-vinylcyclobutanones rearrange mainly by a 1,2-acyl migration to give cyclopentenones while 2-vinylcyclobutanones lacking 2-alkyl substituents undergo a 1,3-acyl migration to produce cyclohexenenes: the former rearrangement can be used to produce angularly substituted fused bicyclic systems.
