Abstract: | Summary. The polyfunctionality and conformational rigidity of carbohydrates make this class of compounds ideal scaffolds for the production
of sortiments1 of bioactive compounds. Examples of carbohydrate-derived peptidomimetics of biological interest, such as somatostatin agonists
and integrin antagonists, are presented. In order to have access to solid phase supported sortiments of compounds, orthogonally
protected or unprotected carbohydrates were linked to polymers and reacted in the solid phase employing different regioselective
strategies. Original bicyclic and tricyclic glycidic scaffolds were easily obtained starting from natural sugars such as D-arabinose and D-fructose. Manipulation of these conformationally blocked compounds afforded different carbohydrate-based derivatives, among
which azidoacids are useful precursors of β-turn peptidomimetics.
