BIS-MODIFIED BICYCLIC NUCLEIC ACID ANALOGS

摘要

The present disclosure describes bis-modified bicyclic nucleosides and oligomeric compounds that can be prepared comprising at least one of these bis-modified bicyclic nucleosides. More particularly, the bis-modified bicyclic nucleosides have at least one substituent group at the 5'-methylene and on the bridge methylene and can be chiral. These bis-modified bicyclic nucleosides are expected to be useful for enhancing one or more property of oligomeric compounds including for example enhancing nuclease resistance.
