摘要

Summary: The N-phenylsulfonyl derivative (2) of the previously unknown fused heterocycle 4H-furo [3, 4-blindole is synthesized from indole-3-carboxaldehyde(2) in 28% yield and undergoes a Diels-Alder reaction with benzyne to give 5H-benzo [b] carbazole(11) in-33% yield after deoxygenation and deprotection.
