Abstract

The invention provides new reagents and an improved process for synthesizing oligonucleotides that contain methylphosphonate internucleoside linkages. The reagents and process utilize a nucleoside base protecting group that is stable under oligonucleotide synthesis conditions, but which can be removed under more mild conditions than existing protecting groups.
