β-d-threo- and 4-deoxy-4-amino-α-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 and d-allal-derived allyl N-nosyl aziridine , respectively.
