  exo-Imino to endo-Iminocyclitol Rearrangement. A General Route to Five-Membered Antiviral Azasugars

  摘要：

  A facile synthesis is reported for five-membered iminocyclitols which allows for variation in stereochemistry at all the chiral centers, diverse C-1- and N-substitution, and the potential for a three-component combinatorial process. The key step is inversion at the C-4 stereocenter (L-lyxo sugar -> D-ribono azasugar). The exo-imino to endo-iminocyclitol process was extended to the D-lyxo and the D- and L-hexose series. Some analogues were found to be more potent than N-butyl DNJ and N-nonyl DNJ in antiviral activity.

  A method of synthesizing stereochemically defined iminocyclitol comprises replacing an intraring oxygen in a cyclic sugar by an intraring imine to form an iminocyclitol, wherein said iminocyclitol has a defined stereochemical configuration different from a stereochemical configuration of the cyclic sugar. The invention also provides combinatorial libraries of iminocyclitol compounds, allowing for diverse C1 and N-substitution. In addition, provided are methods of treating viral infections with iminocyclitols compounds.
