Various C‐2 branched glycoconjugates were obtained from 2‐iodoglycals via Pd‐catalyzed azidocarbonylative coupling reaction. Several O‐protected glycal substrates including disaccharides were tolerated. The glyco‐acyl azides obtained were employed as a synthetic intermediary in the synthesis of new glycoureas with different functional groups.
