Intramolecular transannular dipolar cycloaddition was investigated as a key step in a syntheticapproach to the core of the sarain alkaloids; although the use of an azomethine ylide was unsuccessful with the chosen aldehyde substrate, cycloaddition with a nitrone did give the alternative regioisomeric bridged cycloadduct.
