Expedient Synthesis of 9,10-Phenanthrenes via LiOPiv-Promoted and Palladium-Catalyzed Aryne Annulation by Vinyl Triflates

Abstract

A novel LiOPiv-promoted and palladium-catalyzed Formal [2+2+2] annulation reaction of vinyl triflates and o-silylaryl triflates via aryne intermediates has been developed. This methodology affords good to excellent yields of 9,10-substituted phenanthrenes (including cyclohexa[l]phenanthrenes) and is tolerant of a variety of functional groups such as ester, cyano, and ketone.
