Diethyldithiodicarbonate (DDD), a cheap and easily prepared compound, is found to be a
rapid and efficient sulfurizing reagent in solid phase synthesis of phosphorothioate
oligodeoxyribonucleotides via the phosphoramidite approach. Product yield and quality
based on IP-LC-MS compares well with high quality oligonucleotides synthesized using
phenylacetyl disulfide (PADS) which is being used for manufacture of our antisense drugs.
