Abstract

It is shown that the reaction of 2,3,5-trimethyl-6-aminoindole with 1,3-diketones is a convenient method for the preparation of angular 1H-pyrrolo[2,3-f]quinolines, while the presence of a methyl group on the pyrrolic nitrogen atom of the initial indole as a result of steric hindrance completely blocks cyclization to the corresponding pyrroloquinolines.
