Abstract
Interaction of 6,7-dichloroquinoline-5,8-dione (I) with active methylene compounds and pyridine (or substituted pyridine) afforded indolizino[2,3-g]quinoline-5,12-diones (III, IV). When quinoline or isoquinoline was used instead of pyridine in the above reaction benzo[5,6]- or benzo[7,8]-indolizino[2,3-g]quinoline-5,12-diones (V, VI) were obtained. Their structure has been ascertained through elemental and spectral analysis.
