  Preparation of Disaccharide Haptens Corresponding toSalmonellaSerogroups B and D

  摘要：

  The properly protected ethyl 1-thio-abequopyranoside 11 and ethyl 1-thio-tyvelo-pyranoside 26 were prepared by a sequence of reactions, the key step of which was the regioselective hydride-mediated ring-opening of the cyclic sulfate function in compounds 8 and 18. Iodonium ion-assisted glycosylation of allyl mannopyranoside 30 with the individual ethyl 3,6-dideoxy-1-thio-D-hexopyranoside donors 11 and 26 furnished, after deprotection, the respective allyl 3-O-(alpha-D-abequopyranosyl)-alpha-D-mannopyranoside 1 and allyl 3-O-(alpha-D-tyvelopyranosyl)-alpha-D-mannopyranoside 2.
