ChemInform Abstract
On photooxygenation the naphthalene derivatives (I) give the corresponding endoperoxides (II) and (III) in excellent yields. The diastereoselectivity of the singlet oxygen attack is determined and the directing effect of the various substituents R is rationalized in terms of attraction or repulsion in the transition state through electronic and steric effects.
