2-Azido-3,4;6,7-di-O-isopropylidene-αd-glycero-d-talo-heptopyranose

Abstract

In the title compound, C13H21N3O 6, the six-membered ring adopts a twist-boat conformation with the azide group in the bowsprit position. The azide group is disordered over two sets of sites in a 0.642 (10):0.358 (10) ratio. The crystal structure consists of O - H⋯O hydrogen-bonded trimer units. The absolute configuration was determined from the use of d-mannose as the starting material.
