摘要：

We report a metal-free, oxidant-free, highly regioselective halogenations protocol (chlorination, bromination and iodination) to amidoquinolines using N-halosaccharin derivatives. Various amidoquinolines are tolerated by the method and delivered C5-haloamidoquinoline derivates in excellent yields. A homo and hetero bis-halogenation protocol has also been established. Late stage drug molecule diversification has also been demonstrated using the developed protocol.
