A simple “heavy” lipophilic tag readily prepared from inexpensive gallic acid can greatly simplify the purification steps in oligosaccharidesynthesis through liquid-liquid extraction (LLE) using two immiscible organic solvents. By introducing the tag at the anomeric position of the carbohydrate acceptor, this simple LLE purification can be advantageously carried out at each step throughout the synthetic
