Rhodium-Catalyzed Oxidative Benzannulation of N-Adamantyl-1-naphthylamines with Internal Alkynes via Dual C–H Bond Activation: Synthesis of Substituted Anthracenes
Rhodium-catalyzed oxidative benzannulation of N-adamantyl-1-naphthylamines with internal alkynes to produce highly substituted anthracenes in satisfactory to good yields was developed. The annulation reaction proceeded smoothly under mild conditions in the presence of [Cp*RhCl2]2 as the precatalyst and Cu(OAc)2 as the oxidant.
