An improved process for the preparation of purin-9-ylalkylenoxymethyl phosphonic acids, novel nucleotide analogs, typified by (S)-9-(3-hydroxy-2-phosphonylmethoxypropyl)adenine, also known as (S)-HPMPA. The improved process employs novel intermediates, is shorter and more efficient by virtue of eliminating large scale isomer separations and ion exchange chromatography, and also is applicable to guanine derivatives as well as to adenine derivatives.

Novel ethylene glycol compounds bearing various functional groups are used to prepare oligomeric structures. The ethylene glycol monomers can be joined via standard phosphate linkages including phosphodiester and phosphorothioate linkages. Useful functional groups include nucleobases as well as polar groups, hydrophobic groups, ionic groups, aromatic groups and/or groups that participate in hydrogen-bonding.
