Abstract

Ferrocenyl nitrones derived from aldehydes or oximes react with electron deficient alkenes to give ferrocenylisoxazolidines. 5‐Methoxycarbonylisoxazolidines are further transformed to ferrocenyl‐pyrrolidinones by reductive cleavage. The regio‐ and stereoselectivity of the reactions are discussed.

The intramolecular 1,3-dipolar cycloaddition of Ο‰-unmolecular cycloaddition, followed by reductive opening of the isoxazolidine ring, produced five-and seven-membered saturated chiral nitrones is described. Starting materials for this reaction are O-protected chiral cyanohydrins, prepared ring compo
