Auxiliary controlled intramolecular 1,3-dipolar cycloaddition reactions of chiral azomethine ylides

Abstract

Intramolecular 1,3-dipolar cycloaddition reactions of chiral azoniethine ylides obtained by thermal ring opening of chiral aziridines 7a, b and 8a, b are investigated. Synthesis of these aziridines 7a, b and 8a, b is described.
