  A metal‐free and oxidant‐free method for the one‐pot preparation of quinazolin‐4(3H)‐ones enabled by electrochemical oxidation is described. Together with 2‐aminobenzamides, a variety of aldehydes were successfully applied to an acid‐catalyzed annulation and direct anodic oxidation cascade, affording structurally diverse quinazoline‐4(3H)‐ones in good to excellent yields. Additionally, certain alcohols

  描述了一种通过电化学氧化一锅法制备喹唑啉-4（3H）-酮的无金属，无氧化剂的方法。与2-氨基苯甲酰胺一起，已将多种醛成功应用于酸催化的环化反应和直接的阳极氧化级联反应，从而提供了结构多样的喹唑啉-4（3H）-酮，产率高至优异。此外，在电解介质（TEMPO）的辅助下，可以直接使用某些醇类代替相应的醛类来获得相同的最终产品。仔细检查了反应机理，结果强烈表明直接和间接氧化经历不同的途径。作为有效和环保的途径，可以使用各种喹唑啉-4（3H）-ones，该方法的合成效用已通过克级操作证明，并制备了生物活性麦角唑啉酮和截短的厄洛替尼。

  A highly environmentally benign protocol for the synthesis of quinazolinones from anthranilamides and aldehydes via aerobic oxidation was developed in wet DMSO. This protocol is operationally simple, exhibits broad substrate scope, and does not need toxic metal catalysts and bases. In addition, the utility of this transformation was further demonstrated by converting the resulting quinazolinones into

  Electrochemistry has recently emerged as a sustainable approach for efficiently generating radical intermediates utilizing eco-friendly electric energy. An electrochemical process was developed to transform 1,2,4-oxadiazolines under mild conditions. The electrochemical N–O bond cleavage at a controlled oxidation potential led to the selective synthesis of quinazolinone derivatives that could not be

  variety of substituted quinazolin-4(3H)-ones were prepared in 63-91% yields by the palladium-catalyzed cyclocarbonylation of o-iodoanilines with imidoyl chlorides and carbon monoxide. The reaction is believed to proceed via in situ formation of an amidine, followed by oxidative addition, CO insertion, and intramolecular cyclization to give the substituted quinazolin-4(3H)-ones.
