Ruthenium(II)-Catalyzed Tandem C–H Allylation and [3 + 2] Dipolar Cycloaddition to Construct Bridged Tetracycles

The ruthenium­(II)-catalyzed tandem C–H allylation and intramolecular dipolar cycloaddition between azomethine imines and 2-methylidenetrimethylene carbonate is described herein. The initially formed β-substituted allyl fragment could trigger the exotype
