Multicomponent reactions (MCRs) involving pyridines, α-bromo ketones, and silylaryl triflates as aryne precursors were investigated. The reactions could also be extended to isoquinoline or α-bromo ethyl acetate. Substituted pyrido[2,1-a]isoindoles or isoindolo[2,1-a]isoquinolines could be obtained from this routine, which may have potential applications in antitumor drugs and fluorescent material fields

An iron-catalyzed reaction of 2-arylpyridine C–H bond with 2-bromoacetophenone is achieved, providing pyrido[2,1-a]-isoindoles in moderate to good yields. The regioselectivity stems from the domination of hindrance on the regioselective ortho-functionalization of 2-arylpyridines C–H bond.
