摘要: A new synthesis of the indole system has been achieved by chclodehydrogenation amino phenylmalonate heterocycles. Thus, 4-amino coumarins1 a,b or 4-amino-2-quinolones1 c–g are converted to indoles2 with palladium on charcoal in boiling diphenyl ether. The reaction aminocompounds1 carbonate yields fused polycyclic isoquinolones4.
