The Preparation of Optically Active Δ2-Isoxazolines. A Model for Asymmetric Induction in the Non Lewis Acid Catalyzed Reactions of Oppolzer's Chiral Sultam

Good diastereoselectivity (ca. 90/10) is reported in the cycloaddition reactions of Oppolzer's chiral sultam with nitrile oxides.A model is proposed which may apply to other non Lewis acid promoted reactions of this sultam.
