Lauryl glycoside of β‐ D ‐Gic p ‐(1 → 3)‐[β‐ D ‐Glc p ‐(1 → 6)‐] a ‐ D ‐Glc p ‐(1 → 3)‐β‐ D ‐Glc p ‐(1 → 3)‐[β‐ D ‐Glc p ‐(1 → 6)‐] a ‐ D ‐Glc p ‐(1 → 3)‐β‐ D ‐Glc p ‐(1 → 3)‐[β‐ D ‐Glc p ‐(1 → 6)‐]β‐ D ‐Glc p was synthesized through 3 + 3 + 3 strategy. 3‐ O ‐Allyl‐2, 4, 6‐tri‐ O ‐benzoyl‐β‐ D ‐glucopyranosyl‐(1 → 3)‐[2, 3, 4, 6‐tetra‐ O ‐benzoyl‐β‐ D ‐glucopyranosyl‐(1 → 6)‐] 1, 2‐ O ‐isopropylidene‐ a ‐ D ‐glucofuranose was used as the key intermediate which was converted to the corresponding trisaccharide donor and acceptor readily.
