Palladium‐Catalyzed Bicyclization of 1‐(2,2‐Dibromovinyl)‐2‐Alkenylbenzene with Allenyl Malonates

Palladium‐catalyzed bicyclization of 1‐(2,2‐dibromovinyl)‐2‐alkenylbenzene with allenyl malonates has been achieved to afford a series of bicyclic compounds. The protocol involves intermolecular carbopalladation of allenes/cyclization/internal Heck reaction. Three C−C bonds and two rings are formed...

Description
Summary:Palladium‐catalyzed bicyclization of 1‐(2,2‐dibromovinyl)‐2‐alkenylbenzene with allenyl malonates has been achieved to afford a series of bicyclic compounds. The protocol involves intermolecular carbopalladation of allenes/cyclization/internal Heck reaction. Three C−C bonds and two rings are formed in one step.
