ABSTRACT A novel method for the synthesis of 2 or 3-substituted 5,6-dihydro-6,11-dioxo-morphanthridines (2) involving the cyclisation of anilinic acid (1) with PPA/AcOH has been developed. A new heterocyclic system, 2 or 3-Substituted 5,6,11,12-tetrahydrodibenzo[b, f] [1,4]diazocine-6,11-diones (4) has been synthesized with excellent yields.
摘要 已开发出一种合成 2 或 3-取代的 5,6-二氢-6,11-二氧代-morphanthridines (2) 的新方法,该方法涉及苯胺酸 (1) 与 PPA/AcOH 的环化。一种新的杂环系统,2 或 3-取代 5,6,11,12-四氢二苯并[b, f] [1,4]diazocine-6,11-diones (4) 已以优异的产率合成。
