An efficient Cu-catalyzed synthesis of quinazolines via the C–N bond formation reactions between N–H bonds of amidines and C(sp3)–H bonds adjacent to sulfur or nitrogen atoms in the commonly used solvents, such as DMSO, DMF, DMA, NMP or TMEDA, followed by intramolecular C–C bond formation reactions was developed for the first time.
本研究首次开发了一种铜催化喹唑啉类化合物的高效合成方法,即在 DMSO、DMF、DMA、NMP 或 TMEDA 等常用溶剂中,通过脒的 N-H 键与邻近硫或氮原子的 C(sp3)-H 键之间的 C-N 键形成反应,然后进行分子内 C-C 键形成反应。
