Convergent synthesis of two trisaccharidesrelated to the cytotoxictriterpenoidsaponinisolatedfrom Pithecellobium lucidum is reported. The trisaccharides are synthesized in the form of their propargyl glycosides to leave the scope for further glycoconjugate formation through various multi-component reactions. A simple protecting group manipulation is followed using commercially available monosaccharides
