The synthesis and characterization of new methyl cyclopropano furanosides are described. A fused cyclopropane ring bearing a hydroxymethyl group was constructed at the 3,4-positions of the furanose ring by a consecutive 1,2-hydride shift-enolization-cyclopropanation reaction starting from a sugar disulfonate under mild reaction conditions with Mg(OMe)2 in a one-pot manner.
