title: Synthesis of fluorous and nonfluorous polycyclic systems by one-pot, double intramolecular 1,3-dipolar cycloaddition of azomethine ylides.
abstract: [reaction: see text]. Under microwave irradiation, a one-pot, double intramolecular [3 + 2]-cycloaddition reaction of azomethine ylides leads to formation of a novel hexacyclic ring system. The major diastereomer is isolated, and its stereochemistry is determined by X-ray crystal structure analysis.
