Cu-Fe spinels promoted the Ferrier rearrangement of 2-nitroglycals with several O-nucleophiles. 2,3- Unsaturated carbohydrate derivatives were prepared by the reaction of 3,4,6-tri-O-acetyl-2-nitroglucal and alcohols in the presence of 5 % of CuFe2O4

This is the first report on the Ferrier rearrangement of 2-halo-glycals with S-nucleophiles. We present herein the selective synthesis of new 2-iodo-2,3-unsaturated O- and S-glycosides. We obtained in good yields and high anomeric selectivity a-glyco

Herein we present the synthesis and structural analysis of novel -O-(N)-glycosides. The biphasic reaction of NHS and acetobromo-α-D-glucose or D-galactose gives the β anomer glycoside in a straightforward manner. Further hydrazinolysis and condensa

We present the selective synthesis of new 2-iodo-2,3-unsaturated O- and S-glycosides. This is the first report on the Ferrier rearrangement of 2-halo-glycals with S-nucleophiles. We obtained α-glycosides in good yields and with high anomeric selecti
