Asymmetric synthesis of amino sugars. Part 2. A novel versatile approach to the chiral non-racemic synthesis of 2-amino-2-deoxy sugars. Preparation of L-glucosamine, L-mannosamine and L-talosamine derivatives
Abstract
A novel methodology for asymmetric synthesis of 2-amino-2-deoxy sugars is developed, starting from readily available chiral building block 1 and 2,3-O-isopropylideneglyceraldehyde 2, via
