以碳酸乙烯亚乙酯为原料, 通过锰催化的喹唑啉酮的邻位碳氢烯丙基化反应, 制备得到了一系列具有潜在应用价值的芳基丁烯醇类产物. 该反应表现出较好的底物普适性和顺反立体选择性, 拓展了锰催化C—C偶联反应的类型.

关键词: 锰催化, 烯丙基化, 喹唑啉酮, C—H活化

The ortho-allylation of quinazolinones with 4-vinyl-1,3-dioxolan-2-one via manganese catalysis has been described. A series of allylation products with potential applications have been obtained. This protocol is also highlighted by good compatibility of functional groups and excellent E/Z selectivity. This work broadens the scope of Mn-catalyzed C—C coupling reactions.

Key words: manganese-catalyzed, allylation, quinazolinones, C—H activation
