Abstract

The synthesis of four deuterated sialic acids and their 1, 7-lactones has been performed in two ways, one based on sialic acid classical chemistry, and the other involving a direct exchange of the unlabeled acyl group of N-acetylneuraminic acid with a labeled one mediated by a perfluorinated amide. The final lactonization is promoted by benzyloxycarbonyl chloride.
