A compound of the formula (1) wherein R
1
is a group removable by hydrogenolysis, and wherein R
2
is OH or R
2
is —NHR
3
wherein R
3
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.
