Intramolecular Hetero Diels-Alder with inverse electron demand: Synthesis of pyrano[3,2-b]indole derivatives

Pyrano[3,2-b]indole derivatives 4, 5 and 8 have been synthesised in good yields from 1-acetyl-2-benzylidene-1H-indol-3(2H)-one 3 and 7 via an intramolecular Hetero Diels-Alder reaction with inverse electron demand.

Synthesis of pyrano[3,2-b]indole derivatives based on intramolecular hetero-Diels-Alder of 2-benzylidene-2,3-dihydro-1H-indol-3-ones

Pyrano[3,2-b]indole derivatives 2-6 were synthesized in good yields from 1-acetyl-2-benzylidene-2,3-dihydro-1H-indol-3-ones 8 and 13-15 by an intramolecular hetero-Diels-Alder reaction. The structures of compounds 2a, 3a, 4, 5, and 6 were unambiguously es
