摘要

介绍了一种高效的单锅定量程序，该程序是在 90 °C 无溶剂条件下，在均质溶液中，以 2-羟基萘-1,4-二酮、苯-1,2-二胺、芳香醛和丙二腈为催化剂，在[(EtO)3Si(CH2)3N+H3][CH3COO-]碱性离子液体存在下，通过四组分缩合反应制备苯并[a]吡喃并[2,3-c]吩嗪衍生物。该方法具有步骤简单、产率高、反应时间短和对环境无害等优点。[(EtO)3Si(CH2)3N+H3][CH3COO-]可多次回收和重复使用而不会丧失其活性。

[(EtO)3Si(CH2)3N+H3][CH3COO−] as Basic Ionic Liquid Catalyst Promoted Green Synthesis of Benzo[a]pyrano[2,3-c]phenazine Derivatives in Homogenous Solution

An efficient, one-pot quantitative procedure for the preparation of benzo[a]pyrano[2,3-c]phenazine derivatives from four-component condensation reaction of 2-hydroxynaphthalene-1,4-dione, benzene-1,2-diamine, aromatic aldehydes, and malononitrile in the presence of [(EtO)₃Si(CH₂)₃N⁺H₃][CH₃COO⁻] as basic ionic liquid as catalyst in homogenous solution under solvent-free conditions at 90 °C is described. Simple procedure, high yields, short reaction times, and an environmentally benign method are advantages of this protocol. The [(EtO)₃Si(CH₂)₃N⁺H₃][CH₃COO⁻] can be recovered and reused several times without loss of its activity.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
