A photoannulation route to naphthalenes from cyclic ketones
摘要:
A three-step naphthalene annulation of cyclic ketones has been developed. Aldol condensation with an aromatic aldehyde followed by Wittig olefination produces a 1,3-diene, which undergoes oxidative photocyclization to produce a naphthalene derivative. Ketone ring sizes of C5 to C8 were annulated successfully. The sequence was also applied successfully to three methyl-substituted derivatives and one polycyclic case.
