Abstract
Indole 2,3-dienolate derived by deprotonation of 1,2-dimethylindole-3- carboxaldehyde is shown to be useful 1,4-dipole synthon (anionic indol o-2,3-quinodimethane) which undergoes facile cycloaddition with wide r ange of dienophiles affording substituted carbazoles in highly regiosp ecific fashion.
