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

A novel three-component assembly involving benzynes has beendeveloped for the synthesis of pyrido[2,1- A]isoindolesin moderate yields. Reaction conditions have been optimized andthe scope of the reaction has been studied. A plausible mechanismhas been proposed to account for the three-component reaction.
