Abstract
Novel pyrrolidine monomers bearing various functional groups are used to prepare oligomeric structures. The pyrrolidine 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.
