Stereoselective photocycloaddition of alkenes to naphthalene rings assisted by hydrogen bonding
Introduction of a hydrogen-bonding substituent to 1-cyanonaphthalene and alkene resulted in the selective formations of endo-photocycloadducs. Furthermore, the yield and selectivity were improved as the reaction temperature was lowered.
