An improved synthesis of rupintrivir (AG7088) was accomplished using three amino acids (l-glutamic acid, d-4-fluorophenylalanine, and l-valine) as the building blocks. The key fragment ketomethylene dipeptide isostere was constructed with the valine derivative and phenylpropionic acid derivative, followed by coupling with a lactam derivative and an isoxazole acid chloride to provide AG7088 totally in eight steps.
对rupintrivir (AG7088) 的改进合成使用了三种氨基酸(l-谷氨酸、d-4-氟苯丙氨酸和l-缬氨酸)作为构建块。关键片段酮亚甲基二肽异构体通过缬氨酸衍生物和苯丙酸衍生物的构建而成,随后与内酰胺衍生物和异恶唑酸氯化物偶联,最终在八个步骤中合成出AG7088。
