The present invention relates a cyclic glycolipopeptide compounds useful as adjuvants in immunogenic compositions for vaccination. The cyclic glycolipopeptides bear  1,2,3- triazole or C4-homologue moieties on glucose unit of a NOD2 agonistic peptide moiety and have high potential of immuno-modulating properties for use as  adjuvants in vaccine formulations. The present invention discloses a process for the preparation of these cyclic glycolipopeptide analogues and their intermediates.
