for the construction of cyclopropane‐fused dihydroquinolines was established by a novel Povarov‐typethree‐component reaction of aromatic aldehydes, anilines and cyclopropenes in the presence of trifluoromethanesulfonic acid. The reaction proceeded in a regioselective and diastereoselective manner. Furthermore, the dihydroquinolines were smoothly converted to benzazepine derivatives via a ring opening/isomerization
