A newsynthesis of the methyl-branched sugar axenose is described. Axenose is found in the antibiotics axenomycin, dutomycin, and polyketomycin. The synthesis is based on additions of organometallic reagents to pentodialdo-1,4-furanosides and allows the preparation of derivatives of methyl α-l-axenoside which are protected at the tertiary C-3 hydroxyl group. Conversion to thioglycoside derivatives for
