  Approaches to the synthesis of CF2-analogues of 2-deoxy-2-aminoglycosides

  摘要：

  The preparation of a fluorinated C-glycosidic analogue of a 2-deoxy-2-acetamido-D-altrose is described. The synthetic sequence involves the addition of a difluoroenoxysilane to a D-glucal, an epoxidation of the resulting unsaturated CF2-glycoside and a ring-opening reaction with TMSN3. An Overman rearrangement of the unsaturated intermediate is also described. (C) 2009 Elsevier Ltd. All rights reserved.

  Synthesis of α-CF₂-mannosides and Their Conversion to Fluorinated Pseudoglycopeptides

  摘要：

  A methodology allowing the synthesis alpha-CF(2)-rnannosides, based on the addition of a difluoroenoxysilane to a glycal followed by a dihydroxylation reaction, is described. The resulting 2,2-difluoro-2-mannosylacetate is converted into two pseudoglycopeptides which may act as E- and P-selectin inhibitors.
