The powerful chemo-enzymatic synthesis of the pentadecasaccharide hapten involved in the first synthetic carbohydrate-based vaccine candidate against endemic shigellosis is reported. The high yielding site-selective α-D-glucosylation of a lightly protected disaccharide by an engineered transglucosylase-sucrose system gave a trisaccharide, which was chemically elongated by an efficient [5+5] process.
