Since Norrish in the 1930's discovered the type I and type II photochemical
reactions of ketones there have been numerous studies on both
alkyl and aryl ketones. The photochemistry of β, y-epoxyketones has been
little studied in contrast to the exhaustive studies with the photochemistry
of α, βepoxyketones. A general mechanism has been suggested to explain
photochemical reactions of β,Y-epoxyketones, which is not in full agreement
with the results obtained during the photolysis of steroidal β,y-epoxyketones....
