  • Title: Highly enantioselective nitrone cycloadditions with 2-alkenoyl pyridine N-oxides catalyzed by Cu(II)-BOX complexes.
    Author: Barroso S, Blay G, Muñoz MC, Pedro JR.
    Journal: Org Lett; 2011 Feb 04; 13(3):402-5. PubMed ID: 21175140.
    Abstract:
    Enantioselective nitrone cycloadditions with 2-alkenoyl pyridine N-oxides as dipolarophiles have been reported. The reaction is catalyzed by Cu(II)-BOX complexes to give the expected isoxazolidine products with high diastereo- and enantioselectivity.
