L-Glucosederivatives are prepared by two different routes. The first involves a modification of the previously reported multi-step approach by Shiozaki8, starting from a D-glucurono-1,5-lactone derivative, resulting in the isolation of 2,3,4,6-tetra-O-benzyl-L-glucopyranose. The other route comprises the synthesis of penta-O-acetyl-L-glucopyranose via a highly stereoselective addition of [(phenyl
