various acids and isocyanides. A library of densely functionalized glycomimetics bearing up to 3 carbohydrate units was obtained in high yields and diastereoselectivities. The configuration of the newly formed stereocenter was determined and the diastereoselectivity was rationalized by DFT calculations.
