The intramolecular ortho photocycloaddition of 2-acetonaphthones has been achieved with high enantioselectivity. The catalytic use of a chiral Lewis acid was critical for the success of the reaction and its mode of action has been elucidated by mechanistic experiments and calculations. The primary photocycloaddition products underwent photochemically or thermally a variety of consecutive reactions
