The synthesis of N-acyl-5-halo-8-aminoquinolines has been realized by directly employing 8-aminoquinolines and acyl halides (Cl, Br, I) with copper catalysis. The construction of the target products involves domino N-acylation and C5–H halogenations of the 8-aminoquinoline, wherein the acyl halides act as the donors of both acyl and halide atoms, which enables the first access to the step efficient
N-酰基-5-卤代-8-氨基喹啉的合成已经通过在铜催化下直接使用8-氨基喹啉和酰基卤(Cl,Br,I)来实现。目标产物的构建涉及8-氨基喹啉的多米诺N-酰化和C5-H卤化,其中酰基卤既是酰基原子又是卤原子的供体,这使得该方法可以首次有效地合成5-卤代N-酰基喹啉。
