A one-step synthesis of pyrrolo[1,4]benzodiazepine dilactams has been developed. The high yielding method involvesdirect coupling of unprotected anthranilic acids with proline esters. This transformation was successfully applied in the first total syntheses of boseongazepines B and C as well as oxoprothracarcin and limazepine E.
吡咯并[1,4] 苯并二氮杂二内酰胺的一步合成已被开发出来。高产方法涉及将未保护的邻氨基苯甲酸与脯氨酸酯直接偶联。这种转化成功地应用于第一次全合成 Boseongazepines B 和 C 以及oxoprothracarcin 和 limazepine E。
