A one-pot synthesis of 4(3H)-quinazolinones from terminal alkynes, sulphonyl azide, o-iodoanilines, and carbon monoxide has been developed. This cascade process includes the copper-catalyzed three-component reaction of alkyne, azide and amine, the palladium-catalyzed carbonylation, and the Lewis acid catalyzed hydrolysis of sulfonamide.
已经开发了由末端炔烃,磺酰基叠氮化物,邻碘苯胺和一氧化碳一锅合成4(3 H)-喹唑啉酮的方法。该级联过程包括炔烃,叠氮化物和胺的铜催化三组分反应,钯催化的羰基化反应和路易斯酸催化的磺酰胺水解。
