Synthesis of 9-methoxycarbonyl-7H-[1]benzothieno[4,5,6-ij][2,7]naphthyridin-7-one (3)—an analogue of kuanoniamine A (1)—via hetero Diels–Alder reaction of crotonaldehyde N,N-dimethylhydrazone with 2-methoxycarbonylbenzo[b]thiophene-4,7-dione and subsequent annelation, is described. The Diels–Alder reaction produced only the adduct with the desired regiochemistry, the structure of which was verified
合成 9-甲氧羰基-7 H- [1]苯并噻吩并[4,5,6- ij ] [2,7]萘啶-7-one(3)-类似物宽胺(1)-通过杂Diels-Alder反应巴豆醛N,N-二甲基hydr 和 2-甲氧基羰基苯并[ b ]噻吩-4,7-二酮以及后续的匿名处理。Diels-Alder反应仅生成具有所需区域化学的加合物,其结构已通过2D-NMR实验验证。
