title: Recent progress in oligonucleotide synthesis.
abstract: It was found that some improvements in oligoribo- and oligo-2'-deoxyribonucleotide synthesis via the phosphotriester approach could be achieved using the p-nitrophenylethyl group for phosphate protection due to its stability in the condensation step and its clean removal of DBU and DBN respectively. Recent results will prove the synthetic advantages over known procedures.
