Irradiation of acenaphthylene (ACN) and p-chloranil with > 420 nm light in 1,2-dichloroethane gives two interconvertible anomeric naphthopyranylhemiacetals in high yields (> 70%), whereas irradiation of ACN with other 1,4-benzoquinones does not afford this type of products. The above products will result from photochemical formation of an oxetane followed by its hydration. These products are stereoselectively
