title: Click glycoconjugation of per-azido- and alkynyl-functionalized beta-peptides built from aspartic acid.
abstract: Azide- and alkynyl-containing homo-beta(3)-peptides, of up to six residues in length, were synthesised in solution from aspartic acid. Their subsequent conjugation with monosaccharides bearing an azide or a terminal alkyne function was efficiently achieved by copper-mediated cycloadditions leading to two novel families of small glycoclusters. These compounds represent ideal tools to explore carbohydrate-mediated multivalent interactions.
