| Abstract: | A series of novel quinoline derivatives having a spirocyclopropyl ring can be synthesized by one‐pot, three‐component aza‐Diels–Alder reactions of arenecarbaldehydes, arylamines, and methylenecyclopropanes (MCPs) using a heterogeneous solid acid catalyst, montmorillonite KSF, under mild reaction conditions in good to excellent yields. |
