摘要:
Synthesis of Benzyl 4‐O‐benzyl‐2,6‐dideoxy‐α‐ and ‐β‐D‐arabino‐hexopyranosideStarting with the glucosane derivative 1 a convenient synthetic sequence for the preparation of both the benzyl protected 2,6‐dideoxy‐D‐arabino‐hexopyranose anomers 10 and 11 is presented.
The synthesis of mono- and difluorinated 2,3-dideoxy-d-glucopyranoses
摘要:
The synthesis of 2,3-dideoxy-2,3-difluoro-D-glucose and 2,3-dideoxy-3-fluoro-D-glucose is reported in, respectively, 5 and 6 steps from D-glucal, using a fluorination strategy. (C) 2014 Elsevier B.V. All rights reserved.

acceptor. Bernet et al. have demonstrated its capability to perturb OH···O intramolecularhydrogen bonds (IMHBs), using conformationally rigid carbohydrate scaffolds including levoglucosan derivatives. These investigations are supplemented here by experimental and theoretical studies involving six new levoglucosan derivatives, and complement the findings of Bernet et al. However, it is shown that conformational
