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.

carboxylic acids with amines was developed for the synthesis of a broad scope of amides in a simple, mild, highly efficient, robust and practical manner (>110 examples, >90% yields in most cases). The direct click reactions of acids and amines on a gram scale are also demonstrated using an extremely easy work-up and purification process of washing with 1 M aqueous HCl to provide the desired amides in
