  摘要：

  A series of 1,4-dibenzyl-1,2,3,4-tetrahydroquinoxaline-6,7-dione derivatives (6a-6c) were electrosynthesized. In the present work, electrochemical oxidation of catechols 1a-1d in the presence of the N-1,N-2-dibenzylethane-1,2-diamine (3) as a nucleophile, has been studied in aqueous solutions using cyclic voltammetry and controlled-potential coulometry (CPC) methods. Various parameters such as the applied potential, pH of the electrolytic solution, cell configuration and also purification techniques, were carried out to optimize the yields of corresponding products. New quinoxaline-6,7-dione derivatives were synthesized in excellent yield using an electrochemical procedure coupled with a Schiff base as a facile, efficient and practical method.

  electrochemical oxidation of different catechols were carried out in the presence of N,N′-dibenzylethylenediamine (DBEDA) in a phosphate buffer/acetonitrile solution for the synthesis of different new dibenzyltetrahydroquinoxalinedione derivatives. The oxidation of catechol (1a), 2,3-dihydroxybenzoic acid (1e), and 3,4-dihydroxybenzoic acid (1d) led to the same product, probably due to the decarboxylation reaction

  在N，N'-二苄基乙二胺（DBEDA）存在下，在磷酸盐缓冲液/乙腈溶液中进行了不同儿茶酚的化学和电化学氧化反应，以合成不同的新二苄基四氢喹喔啉二酮衍生物。邻苯二酚（1a），2,3-二羟基苯甲酸（1e）和3,4-二羟基苯甲酸（1d）的氧化产生相同的产物，这可能是由于中间体的脱羧反应所致。以前已经报道了3,4-二羟基苯甲酸（1d）的氧化脱羧反应，而2,3-二羟基苯甲酸（1e）的意外氧化脱羧反应），这是首次报告存在DBEDA的情况。
