  Synthesis of Dimer Phosphoramidite Synthons for Oligodeoxyribonucleotide Phosphorothioates Using Diethyldithiocarbonate disulfide as an Efficient Sulfurizing Reagent

  摘要：

  An efficient solution phase synthesis of deoxyribonucleoside phosphorothioate dimers utilizing phosphoramidite approach is described. Diethyldithiocarbonate disulfide (DDD) was found to be an efficient sulfurizing reagent in the conversion of phosphite triesters to phosphorothioate triesters.

  Investigation of a Facile Synthetic Method for Phosphorothioate Dimer Synthons In Oligonucleotide Phosphorothioates Synthesis

  摘要：

  A facile synthetic method of a phosphorothioate dimer block was investigated. Dinucleoside phosphite triester intermediates were obtained in one-pot synthesis by the coupling of a protected nucleoside bearing free 5'-OH and a protected nucleoside bearing free 3'-OH in the presence of phosphorous trichloride (PCl3) and 1,2,4-triazole. The intermediates were easily sulfurized to afford the desired phosphorothioate dimer blocks in 33-64% overall yields.
