摘要：

An unprecedented substrate-dependent [5+1] annulation of 2-isocyanochalcones with nitroalkanes was developed for the efficient synthesis of functionalized quinolines and 3-nitrodihydroquinolines. This transformation delivers both the aromatic and dihydroquinolines by selectively elimination or retention of the nitro group. Moreover, 3-nitroquinolines and tricyclic pyrrolo[2,3-c]quinolines were conveniently constructed from the resulting 3-nitrodihydroquinolines through a single operation, respectively.
