  • The use of 2-deoxy-2-trichloroacetamido-d-glucopyranose derivatives in syntheses of oligosaccharides
    作者:Géraldine Blatter、Jean-Marie Beau、Jean-Claude Jacquinet

    trichloroacetimidate and its O-benzylated analogue were tested as glycosyl donors in the reaction with a set of sugar acceptors unsubstituted on O-3 and O-4, typically encountered in the synthesis of oligosaccharides. Glycosides were obtained in good to excellent yields with only a slight excess (1.1-1.2 equiv) of the donor, and with a high degree of 1,2-trans stereoselectivity. The corresponding 2-(trich
