Abstract
A rapid method is described for the covalent anchoring of appropriately protected 2′-deoxyribonucleoside-3′-O-succinates to LCAA-CPG, widely used support for solid phase oligonucleotide synthesis. The method involves the reaction of nucleoside-3′-O-succinates with aminoalkyl functions of the support in the presence of improved and commercially available condensing reagent, TBTU or TPP-DTNP to generate fully functionalised polymer supports with excellent nucleoside loadings.
