Abstract
A method is provided for capping failure sequences in oligonucleotide synthesis by phosphitylation. A phosphite monoester is reacted with the 5' or 3' hydroxyl of the failure sequence between successive condensation steps in a synthesis procedure to form a 5' or 3' phosphite diester with the failure sequence. The phosphite diester substituent is inert with respect to subsequent reaction steps in the synthesis of the desired oligonucleotide product.
