    Efficient Enantioselective Synthesis of Dihydropyrans Using a Chiral N,N′-Dioxide as Organocatalyst
    摘要:
    The bifunctional organocatalyst C3 N,N'-dioxide has been successfully applied to the asymmetric cascade Michael/hemiacetalization reaction of alpha-substituted cyano ketones and beta,gamma-unsaturated alpha-ketoesters for the synthesis of multifunctionalized chiral dihydropyrans. The corresponding products were obtained in excellent yields (up to 99%) with high to excellent enantioselectivities (up to 99% ee).
