2-Furyl-4-substituted and furo[2,3-c]-condensed 1,2,3,4-tetrahydro-1,10-phenanthrolines were obtained for the first time from 8-aminoquinolines using the Povarov reaction. Various oxidizing agents were shown to effect the elimination of the substituent at C(4) with subsequent aromatization of the tetrahydroquinoline fragment.
