A novel approach to the synthesis of amino-sugars. Routes to selectively protected 3-amino-3-deoxy-aldopentoses based on pyridinium salt photochemistry

Research has been conducted on the 3-amino-3-deoxy-aldopentoses. The synthesis of these selectively blocked compounds has been carried out and the synthesis strategy based on the pyridinium salt photocyclization-aziridine ring-opening sequence used in preparation of the aminocyclopentendiol derivatives is described.
