Abstract

L'invention concerne un procédé de synthèse de phosphoramidates N3'}P5' oligonucléotidiques par une réaction à échange d'amines de phosphoramidites au cours de laquelle un groupe 3'-amino déprotégé d'une chaîne oligonucléotidique supportée en phase solide est échangé contre la portion amino d'un 5'-phosphoramidite d'un monomère entrant qui possède un groupe 3'-amino protégé. La liaison phosphoramidite internucléotidique résultante est ensuite oxydée pour former une liaison phosphoramidate stable et protégée. Le procédé de l'invention permet d'améliorer considérablement les rendements de production et réduit l'utilisation de réactifs en comparaison aux procédés actuels pour effectuer la synthèse de la classe de composé indiquée ci-dessus.
