A facile and efficient radical cation salt-induced approach to dihydroquinazoline derivatives has been developed by sp3 CH oxidation, and the method uses readily available glycine esters as the starting material under aerobic oxidation conditions without addition of any additive. The present method provides a convenient and practical route for construction of quinazoline skeleton.
通过sp 3 C H氧化已经开发了一种简便有效的自由基阳离子盐诱导的二氢喹唑啉衍生物的方法,该方法在好氧氧化条件下使用容易获得的甘氨酸酯作为起始原料,而无需添加任何添加剂。本方法为构建喹唑啉骨架提供了方便实用的途径。
