An one-pot, solvent-free imino Diels–Alder reaction has been developed under microwave conditions using 1-naphthylamine, aldehydes, and electron-deficient terminal alkynes in the presence of a catalytic amount of In(OTf)3 for construction of benzo[h]quinoline derivatives in short reaction times. The method is clean and operationally simple.
