undergoes rearrangements in several steps. The first, photochemical step involves contraction of the six-membered ring to a five-membered cyclic ketol. Its subsequent rearrangements follow a number of parallel pathways. The main pathway involves the formation of an unstable intermediate bicyclo[3.1.0]hexenone derivative, whose further transformation leads to 4-acetylcyclopentenone via opening of the three-membered
