Methyl 2-deoxy-α- and β-D-threo-pentopyaranosides (Ia, IIa) were prepared. Various conditions for partial methylation of the β-anomer IIa were tried out, leading to methyl 2-deoxy-3-O-methyl-β-D-threo-pentopyranoside (IIc), methyl 2-deoxy-4-O-methyl-β-D-threo-pentopyranoside (IId) and methyl 2-deoxy-3,4-di-O-methyl-β-D-threo-pentopyranoside (IIe). The structures of the products were determined by means of 1H NMR.
