摘要:
Highly stereoselective intramolecular cycloadditions of unsaturated N-substituted oximes, nitrones, and azomethine ylides on the surface of silica gel without a solvent, which have been conducted under microwave irradiation, to produce functionalized tricyclic isoxazolidines fused with a pyrroline or piperidine ring in good yields, are presented.
