Abstract
A three-step naphthalene annulation of cyclic ketones has been developed. Aldol condensation with an aromatic aldehyde followed by Wittig olefmation produces a 1, 3- diene, which undergoes oxidative photocyclization to produce a naphthalene derivative. Ketone ring sizes of C6 to CB were annulated successfully. The sequence was also applied successfully to three methyl-substituted derivatives and one polycyclic case.
