    Graphene oxide (GO) or reduced graphene oxide (rGO): efficient catalysts for one-pot metal-free synthesis of quinoxalines from 2-nitroaniline
    摘要:
    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.

    A highly efficient and versatile method for the synthesis of quinoxaline derivatives with two benzimidazole fragments have been developed on the basis of the ring contraction of 3-(benzimidazo-2-yl)quinoxalin-2(1H)-one with 1,2-diaminobenzene and its various types of substituted and condensed derivatives. Owing to the inter- and intramolecular processes, involving self association, proton exchange

    日期:2014.4
    directed mono ortho-aroylation protocol has been developed using aromatic aldehydes or alkybenzenes as aroyl surrogates. Out of the four available ortho sp2 C–H bonds in the two aryl rings of 2,3-diarylquinoxaline one of the C–H bond is selectively ortho-aroylated. The reaction proceeds via the aroyl radical path in the case of aromatic aldehydes while the alkylbenzenes follow either an aroyl radical or a

  • CaO-catalyzed Aerobic Oxidation of α-Hydroxy Ketones: Application to One-pot Synthesis of Quinoxaline Derivatives
    作者:Takayoshi Hara、Yukihiro Takami、Nobuyuki Ichikuni、Shogo Shimazu

    The aerobic oxidation of α-hydroxy ketones into α-diketones catalyzed by CaO is compared with the same reaction catalyzed by other metal oxides. The catalytic activities of the various metal oxides were proportional to their surface basicities. The direct conversion of α-hydroxy ketones into quinoxalines via CaO-catalyzed aerobic oxidation followed by in situ reaction with 1,2-diaminoaromatics is also achieved. Various types of quinoxalines were synthesized in the presence of the CaO catalyst and molecular oxygen. It was also found that the CaO catalyst was reusable without any loss of its catalytic activity.
    通过比较CaO与其他金属氧化物催化α-羟基酮到α-二酮的好氧氧化反应,研究了CaO的催化活性。各种金属氧化物的催化活性与其表面碱性成正比。通过CaO催化的好氧氧化反应,直接将α-羟基酮转化为喹喉,并在原位与1,2-二氨基芳香化合物反应,也实现了这一转化。在CaO催化剂和分子氧的存在下,合成了各种类型的喹喔啉。还发现CaO催化剂可以重复使用,且没有任何催化活性的损失。
