Photochemical [2 + 2] cycloaddition of enol acetate to cyclohexene led to a 3 : 1 mixture of the tetracyclic photoadducts and which, through reverse aldol reactions, under mild alkaline conditions produced two compounds : a tetracyclic ketone and a tricyclic diketone . Hydrolytic cleavage in methanolic hydrochloric acid of and resulting from irradiation of the enol ether to cyclohexene gave rise to
