A method of N- or O-sulfation of a compound is described whereby the use of a co-solvent system comprising a participating component and a non-participating component, during the sulfation reaction, allows for the non-participating component to actively sequester the participating component away from the sulfated reaction product. This has benefits in decreasing the likelihood or extent of desulfation of the sulfated product and may result in precipitation of the sulfated product thereby allowing for simple collection.

is considered to be better than the low-molecular weight heparin in terms of anticoagulation response, duration of action, and biosafety. However, the synthetic methods previously developed for its manufacture are relatively complicated, thus restricting its extensive use. We report here a potentially scalable and programmable one-pot synthesis of Fondaparinux using the [1,2,2] strategy and designed
