A short and high-yielding synthesis has been devised to prepare C-linked 2-deoxy-2-acetamido-α-D-galactopyranose derivative (I). One of the main advantages of this approach is that it employs com. available and inexpensive D-glucosamine as the starting material. The key steps include a highly stereoselective C-allylation followed by epimerization of the C-4 hydroxyl group. Building block I and orthogonally protected C-linked 2-deoxy-2-acetamido-α-D-galactopyranose derivative were obtained in 44% overall yield (six steps) and 29% overall yield (eight steps), resp. This represents a significant improvement over previously reported syntheses.
