  Stereoselective Synthesis of 2,3-Unsaturated 1,6-Oligosaccharides by Means of a Glycal-Derived Allyl Epoxide and N-Nosyl Aziridine

  摘要：

  beta-D-threo- and 4-deoxy-4-amino-alpha-D-erythro-hex-2-enopyranosyl di- (n = 0) and trisaccharides (n = 1) of types A and B were synthetized by means of a reiterative, completely stereoselective glycosylation process which makes use of the D-galactal-derived allyl epoxide 1 beta and D-allal-derived allyl N-nosyl aziridine 2 alpha, respectively.
