The terminal mono-, di, and trisaccharides of the O-antigen of Vibro cholerae O1 serotype Inaba and Ogawa, have been synthesized in the form of glycosides whose aglycon (dioxolane-type spacer) allows conjugation to carrier proteins by reductive amination. The conjugates obtained were useful models in immunologis studies. On the other hand, an innovative strategy towards the synthesis of the GQ1b[alpha] ganglioside was developed. A number of important structures were successfully prepared as targets directly applicable to the synthesis of gangliosides as well as glycoconjugates using novel synthetic procedures in carbohydrate chemistry.
