The anticoagulant pentasaccharide fondaparinux was synthesized using an improved and optimized synthetic strategy including a convergent [3+2] coupling approach, orthogonal protecting groups and various glycosyl donors. The new methods of glycosylation were also used for controlling the stereochemical configuration and improving the yield of the glycosylation. In addition, HPLC and NMR methods to monitor the process of total synthesis of fondaparinux were employed. This work provides a comprehensive elaboration for the synthesis and analysis of fondaparinux based on related literature, as well as abundant information for the synthesis of heparin-like oligosaccharides. A matter of protection! The anticoagulant pentasaccharide fondaparinux was synthesized using an improved and optimized synthetic strategy. The process of total synthesis was monitored by HPLC and NMR. This work will contribute to continued improvement of the multistep production of fondaparinux and provide abundant information for the synthesis of heparin-like oligosaccharides.

Inoue, Ryo,Matsuda, Sho,Oda, Yoshiki,Ooyama, Hirofumi,Yoshida, Akihiro,Hamasaki, Keita,Yamanoi, Takashi
experimental part, p. 1335 - 1343 (2012/03/27)
This paper describes the synthetic approach to an aromatic a-glycoside as a mimic of neamine, which is a common core structure of some aminoglycoside antibiotics. We achieved the synthesis of the protected precursor of the neamine mimic, 4-(2,6-diamino-2,
Modular synthesis of heparin oligosaccharides
Orgueira, Hernan A.,Bartolozzi, Alessandra,Schell, Peter,Litjens, Remy E. J. N.,Palmacci, Emma R.,Seeberger, Peter H.
, p. 140 - 169 (2007/10/03)
A general, modular strategy for the first completely stereoselective synthesis of defined heparin oligosaccharides is described. Six monosaccharide building blocks (four differentially protected glucosamines, one glucuronic and one iduronic acid) were uti
