1. A method for a synthesis of a nucleic acid comprising a chiral X-phosphonate moiety comprising:
- reacting a molecule comprising an achiral H-phosphonate moiety, a chiral reagent, and a nucleoside comprising a 5′
-OH moiety to form a condensed intermediate; and
converting the condensed intermediate to the nucleic acid comprising a chiral X-phosphonate moiety;
wherein;
the nucleic acid comprising a chiral X-phosphonate moiety is a compound of Formula 1;

Abstract
Described herein are methods of syntheses of phosphorous atom-modified nucleic acids comprising chiral X-phosphonate moieties. The methods described herein provide backbone-modified nucleic acids in high diasteteomeric purity via an asymmetric reaction of an achiral molecule comprising a chemically stable H-phosphonate moiety with a nucleoside/nucleotide.
