A process for the synthesis of a phosphorothioate triester is provided. The process comprises the reaction, in the presence of a coupling agent, of an H- phosphonate with a substrate comprising a free hydroxy group and bonded to a solid support, thereby forming a supported H-phosphonate diester, and subjecting the H-phosphonate diester to sulphur transfer with a sulphur transfer agent.

Cette invention concerne un procédé de synthèse d'un phosphorothioate triester. Ce procédé consiste à faire réagir, en présence d'un agent de couplage, un H-phosphonate avec un substrat qui comprend un groupe hydroxy libre et qui est lié à un support solide. Le H-phosphonate diester supporté ainsi obtenu est soumis à un transfert du soufre au moyen d'un agent de transfert de soufre.
