Synthesis of substituted 2-alkyl-5-hydroxy-1-oxo-1,2-dihydroisoquinolines and their new condensed structures
摘要:
Original methods were developed for the synthesis of 1,2-dihydroisoquinoline derivatives by means of the cyclization of N-substituted hexamethoxycarbonyl-3-propenylpyridin-2-ones either upon action of bases or directly by reaction of hepta(methoxycarbonyl)cycloheptatrienyl potassium with primary amines.

A novel class of fluorescent electron-deficient 5-hydroxyisoquinolones is proposed. The new luminophores are obtained via the reaction of stable and easily available hepta(methoxycarbonyl)cycloheptatrienyl potassium with alkylamines, anilines and acylhydrazines. The new one-pot protocol is efficient with a large scope of primary amines. The solvolysis of N-acylamino substituted 5-hydroxyisoquinolones
提出了一类新型的缺乏荧光电子的5-羟基异喹诺酮类。通过稳定且易于获得的七(甲氧基羰基)环庚三烯基钾与烷基胺,苯胺和酰基肼的反应获得新的发光体。新的一锅法对大量伯胺是有效的。N-酰基氨基取代的5-羟基异喹诺酮类的溶剂分解和随后的反应提供了进一步功能化的途径。几乎所有化合物都显示出荧光,并具有相当大的斯托克斯位移(高达6169 cm -1),除了含硝基和O的化合物取代的产品。在大多数其他情况下,量子产率,吸收和发射最大值,斯托克斯位移均基本上不依赖于异喹啉酮环氮原子上的取代基。
