[0088] 3-O-allyl-2,4,6-tri-O-benzoyl-α-D-mannopyranosyl trichloroimidate [26] (902mg, 1.21mmol) and benzyl A mixture of 3,4,6-tri-O-benzyl-α-D-mannopyranoside [27] (723mg, 1.34mmol) in 1,2-DCE (10mL) over molecular sieves (1.0g of 3 - powder) under argon atmosphere (30 min). The mixture was cooled (0° C.) with continued stirring (10 minutes) before adding TMSOTf (219 μL, 1.21 mmol). After a period of time (10 minutes), Et was introduced3 N (100 μL) and the mixture was filtered. The solvent was evaporated and the residue was subjected to FC (10-50% EtOAc / hexanes) to give the tribenzoate (24) (1.14 g, 84%) as a colorless oil. 1 H NMR (CDCl 3 )δ3.67-3.81, 3.88-3.95, 4.06-4.15, 4.30-4.35 (4m, 12H; H-2 I , -3 I , -4 I , -5 I ,-6a I ,-6b I , -3 II , -5 II ...
