Abstract

Methods for preparing 3′-O-amino-2′-deoxyribonucleoside-5′-triphosphates with reduced 3′-hydroxy-2′-deoxyribonucleoside-5′-triphosphate contamination by converting 3′-(N-acetone-oxime)-2′-deoxynucleoside triphosphate to 3′-O-amine-2′-deoxynucleoside triphosphate by treatment with an aryl-oxyamine and compositions produced therefrom.
