A compound of the formula (I) wherein R1 is a group removable by hydrogenolysis,and wherein R2 is OH or R2 is -NHR3 wherein R3 is a group removable by hydrogenolysis. The compound can be made from fructose by a Heyns-rearrangement. The compound can be used then to make - free D-mannosamine or its salts, - D-mannosamine building blocks and mannosamine containing oligo- or polysaccharides, - N-acetyl-D-mannosamine and its hydrates and solvates, - neuraminic acid derivatives and, - viral neuraminidase inhibitors.

complex glycans with well-defined structures. Herein, we describe a highly efficient chemoenzymatic approach for the first col-lective synthesis of HNK-1-bearing O-mannose glycans with different branching patterns, and their non-sulfated counterparts. The successful strategy relies on both chemical glycosylation of a trisaccharide lactone donor for the in-troduction of sulfated HNK-1 branch, and on substrate
