Abstract Phenylmalonyl heterocyclic compounds such as the quinolones1a–c or3, benzoquinolizinones6a, b and the phenalenones8a, b can be converted to benzofuranes (2a–c, 7a, b and9a, b) by cyclodehydrogenation with Pd/C in boiling diphenyl ether. 2-Phenylchinchonic acid (10) reacts under the same conditions to the dimeric benzofuroquinoline12: the decarboxylated quinoline11 however gives the monomer13.
