Tetrazoles of manno- and rhamno- furanoses

Davis, Benjamin G.,Nash, Robert J.,Watson, Alison A.,Smith, Colin,Fleet, George W. J.

, p. 4501 - 4520 (1999)

The synthesis of [3.3.0] bicyclic tetrazoles derived from D-manno and D- rhamnofuranose staffing from D-mannose, and of L-rhamnofuranose starting from L-rhamnose is described. The key step in the formation of all three examples of this novel class of sugar mimics is an intramolecular [1,3]dipolar cycloaddition of azide and nitrile moieties.
