In summary, many isomeric analogs of ddNs of both D-related and L-related absolute stereochemistries have been synthesized and evaluated in vitro for their antiviral activities. A few of these compounds exhibit potent antiviral activity and, interestingly, belong to both the D and L families. The synthetic methodologies developed will allow accessibility to many more novel modified nucleosides. While some structure-activity relationships are emerging from this work, it is clear that these chiral isomeric nucleosides have opened a new chapter in the field of antiviral nucleosides.
