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....
