Investigation of a facile synthetic method for phosphorothioate dimer synthons in oligonucleotide phosphorothioates synthesis

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.

Oligodeoxyribonucleotide phosphorothioates: Substantial reduction of (N- 1)-mer content through the use of trimeric phosphoramidite synthons

Use of fully protected trimeric phosphoramidite synthons in the synthesis of oligonucleotide phosphorothioate shows a substantial reduction (>85%) in (n-1)-mer content as compared to oligomers synthesized through coupling of standard phosphoramidite monom

Synthesis of dimer phosphoramidite synthons for oligodeoxyribonucleotide phosphorothioates using diethyldithiocarbonate disulfide as an efficient sulfurizing reagent

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.
