title: An efficient oxidizing reagent for the synthesis of mixed backbone oligonucleotides via the H-phosphonate approach.
abstract: The mixture of carbon tetrachloride, N-methyl morpholine (NMM), pyridine and water in acetonitrile has been exploited for the oxidation of dinucleoside H-phosphonate diesters to the corresponding phosphates. The system is found to be inert to the phosphoramidate (P-N) and the phosphorothioate (P-S) linkages and has successfully been applied to the solid phase synthesis of mixed-backbone oligonucleotides (MBOs).
