for the synthesis of substituted quinazolinones from simple and readily available o-aminobenzonitriles and aldehydes in water has been accomplished. I2/base and water play an unprecedented and vital role in the reaction. By electrochemically catalysed hydrolysis of o-aminobenzonitriles, the synthesis of quinazolinones with benzaldehyde was first proposed. The synthetic utility of this method was demonstrated

2-Arylquinzolinones with various substitutions on the aromatic rings were obtained by thermal cyclodehydration/dehydrogenation on reacting anthranilamides and benzaldehydes. The compounds had superior topo I-inhibitory activities but were generally inactive against topo IIα. Among the 6-methyl-, 6-amino-, and 7-methylquinazolinones, 6-amino-substituted derivatives displayed potent cytotoxicity at submicromolar

green and sustainable chemistry for their synthesis. Herein, using I2 in coordination with electrochemical synthesis induced a C–H oxidation reaction which is reported when using water as the environmentally friendly solvent to access a broad range of quinazolinones at roomtemperature. The reaction mechanism strongly showed that I2 cooperates electrochemically promoted the oxidation of alcohols, then
开发在水性介质中使用生物相容性催化剂合成喹唑啉酮的方案将有助于解决使用绿色和可持续化学合成它们的困难。在此,使用 I 2与电化学合成配合会引起 C-H 氧化反应,据报道,当使用水作为环境友好溶剂在室温下获得广泛的喹唑啉酮时。反应机理有力地表明,I 2协同电化学促进醇的氧化,然后有效地将酰胺环化为各种喹唑啉酮。
