A highly efficient palladium-catalyzed domino process has been developed for the synthesis of quinazolino[3,2-a]quinazolinones by forming five new bonds in a single step. Despite the high density and variety of functional groups on the substrates, the tetracyclic quinazolinones were obtained in good to excellent yields.
已经开发了一种高效的钯催化多米诺骨牌工艺,用于通过一步形成五个新键来合成喹唑啉代[3,2- a ]喹唑啉酮。尽管底物上具有高密度和各种官能团,但仍以良好至优异的产率获得了四环喹唑啉酮。
