antitumor drugs among synthetic γ‐lactone‐ and γ‐lactam‐fused 1‐methylquinolin‐4(1H)‐ones, we developed a rapid access to 5‐methyl‐1,3‐dioxolo[4,5‐g]furo[3,4‐b]quinoline‐8,9(5H,6H)‐dione (9) exploiting the γ‐lactone‐fused chloroquinoline 10 previously synthesized in our laboratory (Scheme 1). We also elaborated efficient synthetic methods allowing for a rapid access to two nonclassical bioisosteres
为了在合成的γ-内酯和γ-内酰胺融合的1-甲基喹啉-4(1 H)-酮中发现新的抗肿瘤药物,我们开发了快速获得5-甲基-1,3-二氧戊环酮的途径[4,5- g ]呋喃[3,4- b ]喹啉-8,9(5 H,6 H)-二酮(9)利用先前在我们实验室合成的γ-内酯融合的氯喹啉10(方案1) 。我们还阐述了有效的合成方法,可以快速使用两个非经典的9等生物异构体,即脱氧和碳水化合物类似物。脱氧类似物由γ-内酯融合的喹啉13(也是10的合成前体)分两步制备了11(方案1)。碳水化合物类似物6,9-二氢-5-甲基-9-亚甲基-1,3-二恶唑[4,5- g ]呋喃[3,4- b ]喹啉-8(5 H)-一(12)为容易通过从9-(氯甲基)盐酸消除dioxolofuroquinoline制备15,其中获得通过从三组分一锅反应ñ -甲基- 3,4-(亚甲二氧基)苯胺(= ñ -甲基- 1,3-苯并二恶英-5胺;
