A convenient method for the total synthesis of all the stereoisomers of febrifugine and halofuginone using D-arabinose and L-arabinose as the key starting materials is reported. Apart from the inherent stereocenters in these pentose sugars, the method utilizes the selective hydrogenolysis of the anomeric O-benzyl group, stereoselective Grignard reaction and Wacker oxidation as the key steps to obtain the important precursors for the total synthesis.

(Chemical Equation Presented) The asymmetric dihydroxylation of amino-functionalized vinyl sulfone 19 has been used for the 3-step preparation of 3-hydroxylpiperidine 24 in 86% enantiomeric excess. This enantiomerically enriched building block was used then to synthesize the naturally occurring antimalarial alkaloid febrifugine 1 and its antiangiogenic analogue, halofuginone 3.
