  • One‐Pot Synthesis of Mono‐ and Disubstituted (3<i>H</i>)‐Quinazolin‐4‐ones in Dry Media Under Microwave Irradiation
    作者:Minoo Dabiri、Peyman Salehi、Ali A. Mohammadi、Mostafa Baghbanzadeh

    supported on silica gel is an efficient medium for one‐pot synthesis of (3H)‐quinazolin‐4‐ones in the absence of solvent under microwave irradiation or classical heating. The reaction of orthoesters with 2‐aminobenzamides ends up with the formation of monosubstituted (3H)‐quinazolin‐4‐ones. One‐pot synthesis of disubstituted (3H)‐quinazolin‐4‐ones is also achieved by the reaction of isatoic anhydride
    摘要 硅胶负载的 AlCl3/ZnCl2 混合物是一种有效的介质,可在微波辐射或经典加热下,在无溶剂的情况下,一锅法合成 (3H)-喹唑啉-4-酮。原酸酯与 2-基苯甲酰胺的反应最终形成单取代的 (3H)-喹唑啉-4-酮。二取代(3H)-喹唑啉-4-酮的一锅合成也可以通过靛红酸酐伯胺和原酸酯的反应来实现。

    Quinazolin-4(3H)-one derivatives were synthesized successfully via a one-pot, three component reaction of isatoic anhydride and an orthoester with ammonium acetate or a primary amine catalyzed by silica sulfuric acid under solvent-free conditions. This is the first report on the synthesis of 2-substituted quinazolin-4(3H)-ones by this procedure.
