Graphical Abstract

Working against the clot: The synthetic anticoagulant fondaparinux, a pentasaccharide based on the antithrombin-binding domain of heparin, was prepared in a concise and efficient manner in the shortest route reported to date. The application of one-pot strategies, the use of common intermediates, and the efficient preparation of monosaccharide building blocks from commercial sources are key features of this approach.

Abstract

Fondaparinux, a synthetic pentasaccharide based on the heparin antithrombin-binding domain, is an approved clinical anticoagulant. Although it is a better and safer alternative to pharmaceutical heparins in many cases, its high cost, which results from the difficult and tedious synthesis, is a deterrent for its widespread use. The chemical synthesis of fondaparinux was achieved in an efficient and concise manner from commercially available D-glucosamine, diacetone α-D-glucose, and penta-O-acetyl-D-glucose. The method involves suitably functionalized building blocks that are readily accessible and employs shared intermediates and a series of one-pot reactions that considerably reduce the synthetic effort and improve the yield.
