A novel and efficient Cu(I)-catalyzed ligand- and base-free multipathway domino strategy has been developed for the synthesis of 2-substituted quinazolinones. The reaction utilizes 2-bromobenzamide and multiform substrates such as aldehydes, alcohols, and methyl arenes for a one-pot protocol, whereas TMSN3 is used as a nitrogen source. A wide range of substrate scope, functional group tolerance, and
已开发出一种新颖且有效的Cu(I)催化的无配位体和无碱多径多米诺骨牌策略,用于合成2取代的喹唑啉酮。该反应利用2-溴苯甲酰胺和多种形式的底物,例如醛,醇和甲基芳烃进行一锅法操作,而TMSN 3用作氮源。广泛的基材范围,官能团耐受性和操作简便性是综合有用的功能。
