Abstract
The use of suitably blocked d-glucosamine derivatives possessing the N-allyloxycarbonyl protective group of the amino function represents potential new routes to 1, 2-trans- glucosylations. Both 3, 4, 6-tri-O-acetyl-2-N-allyloxycarbonyl-2-amino-2-deoxy-α-d- glucopyranosyl bromide (2) and 1, 3, 4, 6-tetra-O-acetyl-2-N-allyloxycarbonyl-2-amino-2- deoxy-β-d-glucopyranose (3) could be used in Koenigs-Knorr reactions or Lewis acid ...
