title: Synthesis of oligodeoxyribonucleoside phosphorothioates using Lawesson's reagent for the sulfur transfer step.
abstract: 2,4-Bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson's reagent) efficiently converts the triphosphite intermediate used in the solid-phase synthesis of oligonucleotides into an oligodeoxyribonucleoside phosphorothioate.
