A short synthetic route to phosphonate prodrugs by olefin cross-metathesis, which uses either (acyloxymethyl) or (hexadecyloxypropyl) allylphosphonate building blocks is described. A study of eight ruthenium catalysts including the Ru–indenylidene catalyst, which bears the N-heterocyclic carbene 1,3-bis(2,6-diisopropylphenyl)-4,5-dihydroimidazol-2-ylidene, was undertaken. This method was applied to
描述了使用(酰氧基甲基)或(十六烷氧基丙基)烯丙基膦酸酯结构单元的烯烃交叉复分解来合成膦酸酯前药的短路线。对八种钌催化剂的研究,包括 Ru-茚基催化剂,该催化剂带有 N-杂环卡宾 1,3-双(2,6-二异丙基苯基)-4,5-二氢咪唑-2-亚基。该方法用于合成无环核苷膦酸酯前药。这种策略对于药物和医学研究的进一步用途很有吸引力。
