摘要 2-苯氧(硫)甲基-3-喹啉酸(1a-e)可以在Eaton’s reagent(P2O5-MeSO3H)的作用下进行分子内的闭环反应得到12H-13-氧(硫)-苯并环庚并[1,2-b]喹啉-5-酮类衍生物(2a-e)。该环化工艺比传统的环化工艺所要求的反应条件更加温和,具有反应温度低和产品易分离等特点。 Quinoline-fused ring systems are a back-bone of many natural products and pharmacologically significant compounds and display a broad range of biological activity. For example, the anticancer alkaloid camptothecin ( Figure 1 ) was used as medicine against gastric cancer, tumors of the neck and carcinoma of the urinary bladder.
