- Abstract
Pyrano[3,2-b]indole derivatives 26 were synthesized in good yields from 1-acetyl-2-benzylidene-2,3-dihydro-1H-indol-3-ones 8 and 1315 by an intramolecular hetero-Diels—Alder reaction. The structures of compounds 2a, 3a, 4, 5, and 6 were unambiguously established by X-ray analysis. Compounds 4 and 5 were further aromatized to the corresponding derivatives 16 and 17, respectively.
