Abstract
Abstract The N-phenylsulfonyl derivative ( 2 ) of the previously unknown fused heterocycle 4H-furo[3,4-b]indole is synthesized from indole-3-carboxaldehyde ( 3 ) 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.
