We describe herein a modified procedure for the direct and regioselective synthesis of polyazido-sugars, that currently requires multistep syntheses. This protocol allows to modulate the degree of azidation obtained when the reagents to substrate ratio is changed. (c) 2007 Elsevier Ltd. All rights reserved.
