A method for the synthesis of 2,3-dihydrofuro[3,2-c]quinolines via TfOH or TMSOTf mediated condensation of 2-aminoaryl cyclopropyl ketones with aldehydes has been developed. The reaction proceeds under transition metal or halogen free conditions, giving access to the target molecules in 27-90% isolated yields. Mechanistic study indicates that the reaction sequence involves imine formation, intramolecular
