    Background: An expeditious approach has been developed for the synthesis of two distinct classes of benzopyrones viz. flavones and coumarins under solvent-free conditions. L-Ascorbic acid was found to be an effective promoter under microwave irradiation and conventional heating. Various benzo-α-pyrones and benzo-γ-pyrones were synthesized with overall good yields. The present protocol is highly facile and needs
    背景:已经开发出一种快速的方法来合成两种不同类别的苯并吡喃酮。无溶剂条件下的黄酮和香豆素。发现L-抗坏血酸在微波辐射和常规加热下是有效的促进剂。合成了各种苯并-α-吡喃酮和苯并-γ-吡喃酮,总收率良好。本方案非常容易,不需要柱色谱法纯化,因此在微波辐射和常规加热下均可作为一种有效且兼容的方法。 结果:研究了L-抗坏血酸对黄酮和香豆素合成的催化能力。为此目的,选择了1-(2-羟苯基)-3-芳基-1,3-丙二酮的环脱水和Pechmann香豆素的合成反应。因此,据观察,完成反应需要一摩尔的L-抗坏血酸。在所有情况下,都能以良好至极佳的收率顺利产生所需的黄酮。表明其对各种官能团的优异耐受性。但是,在这些条件下,给电子基团有利于香豆素的合成。仔细分析了所有反应混合物,核磁共振表明转化率高,没有副产物。 结论:我们已经开发了L-抗坏血酸促进的,无溶剂的简单方法,该方法在微波辐射下以及常规加热条件下合成

    作者:Pradip J. Unde、Nitin M. Thorat、Limbraj R. Patil

    A simple and highly efficient protocol for synthesis of flavones from 1-(2-hydroxyphenyl)-3-aryl-1,3-propanediones in presence of ZnO nanoparticles as a promoter in thermal as well as microwave irradiation under solvent-free conditions have been demonstrated. The catalyst is inexpensive, stable, can be easily recycled/reused for several cycles with consistent activity and observed almost same yield confirming the stability of the catalyst. It is believed that the present approach will become an alternative route for the conventional reactions. Because in this protocol, yield is quite high, short reaction time, simple work up, catalyst can be recycled as well as it is free of any hazardous by-products formation during workup.

    在无溶剂条件下,利用ZnO纳米颗粒作为促进剂,在热和微波辐射下,从1-(2-羟基苯基)-3-芳基-1,3-丙二酮合成黄酮类化合物的简单且高效的合成方案已被证明。该催化剂价格低廉、稳定,可轻松回收/重复使用多个周期,并且观察到几乎相同的产率,证实了催化剂的稳定性。相信这种方法将成为传统反应的替代途径。因为在这种方案中,产率相当高,反应时间短,工作简单,催化剂可回收并且在工作过程中不会产生任何有害副产物。

    Vinyl radicals were generated from 3-iodoflavones under a mercury lamp and tandem cyclization reactions occurred with five-membered heteroarenes entailing two consecutive C–C bond formations to synthesize benzo[e]chromeno[2,3-g]indol-13(1H)-one derivatives. The tandem cyclization reactions worked in acetonitrile without any additives such as transition metals, ligands and oxidants, giving rise to a
