    喹喔啉和喹喔啉酮基生色团的光物理性质在多大程度上可预测?
    摘要:
    合成了一系列的生色团,这些生色团包含通过π电子桥连接的喹喔啉或喹喔啉酮电子受体(A)和二烷基氨基苯乙烯基电子给体(D)单元。新型D-π-A,D-π-A-π-D或D-π-A-π-A-π-D系统的电子发射和吸收光谱涵盖从紫外线到近红外的广泛范围。已显示其吸收带的位置和相对强度强烈取决于分子的结构修饰,而溶液中的发射强烈取决于溶质的结构和溶剂极性。量子化学模型为观察到的吸收光谱提供了可靠的描述,并再现了发射带的位置。根据将发光强度与基于喹喔啉和喹喔啉酮的发光蛋白的化学结构以及所用溶剂的极性相关的经验规则,可以证明在质量上可预测发射的量子产率。对主要电子跃迁特征的理论评估表明,通过π桥共轭的D和A单元的同时存在,确保了分子内的电荷转移效应,可能是所研究的所有系统均观察到的类似溶剂致变色作用的基础,而不论其极性如何。

  • A Green Synthesis of Quinoxalines and 2,3-Dihydropyrazines

    Abstract Quinoxaline and dihydropyrazine derivatives were obtained in high yields by simple addition of 1,2-diamines and 1,2-dicarbonyl compounds in water. In some cases, the products spontaneously precipitated from the reaction mixture, making it possible to recover and reuse the mother liquor for further condensations. The very mild reaction conditions, the high yields of the products, and the absence
    摘要 通过在水中简单地添加1,2-二胺和1,2-二羰基化合物,可以高收率获得喹喔啉和二氢吡嗪衍生物。在某些情况下,产物自发地从反应混合物中沉淀出来,使得有可能回收并再利用母液用于进一步的冷凝。非常温和的反应条件,高收率的产品以及不存在任何催化剂,使得该方法成为生产喹喔啉和二氢吡嗪的有效而绿色的途径。 通过在水中简单地添加1,2-二胺和1,2-二羰基化合物,可以高收率获得喹喔啉和二氢吡嗪衍生物。在某些情况下,产物自发地从反应混合物中沉淀出来,使得有可能回收并再利用母液用于进一步的冷凝。非常温和的反应条件,高收率的产品以及不存在任何催化剂,使得该方法成为生产喹喔啉和二氢吡嗪的有效而绿色的途径。

  • Graphene oxide (GO) or reduced graphene oxide (rGO): efficient catalysts for one-pot metal-free synthesis of quinoxalines from 2-nitroaniline
    作者:Babli Roy、Sujit Ghosh、Pranab Ghosh、Basudeb Basu
    DOI:10.1016/j.tetlet.2015.10.065
    日期:2015.12
    A straightforward one-pot preparation of library of quinoxalines from 2-nitroanilines under entirely metal-free conditions is described. Initial reduction of nitroaniline with hydrazine hydrate is efficiently catalyzed by graphene oxide (GO) or reduced graphene oxide (rGO), and further one-pot tandem reactions with 1,2-dicarbonyl compounds or with alpha-hydroxy ketones afford quinoxalines in excellent yields. The catalyst is recovered, characterized, and found to be recyclable for consecutive four runs examined with appreciable conversions. (C) 2015 Elsevier Ltd. All rights reserved.
  • Synthesis of quinoxalines by cyclization of α-arylimino oximes of α-dicarbonyl compounds
    作者:N.P Xekoukoulotakis、C.P Hadjiantoniou-Maroulis、A.J Maroulis
    DOI:10.1016/s0040-4039(00)01847-5
    日期:2000.12
    Heating the title compounds 1 at reflux in acetic anhydride yields quinoxalines 3 and 4 via a presumed aryliminoiminyl radical 5, resulting from homolytic cleavage of the N-O bond in the intermediate ester 2. The observed regioselectivity of the reaction is also rationalized by implicating such a radical. (C) 2000 Elsevier Science Ltd. All rights reserved.
