Synthesis of 2,6-bis(1H-indole-6-yl)-4H-pyran-4-ones via leimgruber-batcho indole synthesis

2,6-Bis(1H-indole-6-yl)-4H-pyran-4-one 4 was synthesized via Leimgruber-Batcho methodology starting from 2,6-bis(4-methyl-3-nitrophenyl)-4H- pyran-4-one 2. Enamine intermediate in this reaction, 3, reacts with aroyl chlorides in the presence of 1,4-diazab
