Indolo[3,2-c]quinolones have been efficiently synthesized via an acid-mediated, one-pot, three-component condensation of arylhydrazines, o-aminoacetophenones, and triazines or nitriles. The synthetic application of this method is showcased by the concise synthesis of isocryptolepine alkaloid and a series of its synthetic analogues with demonstrated cancer cell antiproliferative activities.

acid-mediated one-pot three-component synthesis of indoloquinoline scaffold is developed. This improved version of the process involves electrophilically activated nitroalkanes for the installation of strategic C–C and C–N bonds and ring C assembly. This modification allows the elimination of unnecessary solvent change operations and all steps are carried out in a true, uninterrupted one-pot manner. A

A novel one-pot method based on the sequence of the Fisher reaction between nitroacetophenone and phenylhydrazines, the reduction with metallic tin directly in polyphosphoric acid, and acylation has been developed for the synthesis of indoloquinolines. The obtained indolo-[3,2-c]quinolines are precursors of the analogs of isocryptolepine alkaloid.

One-pot efficient and simple synthesis of γ-carboline derivatives by the Graebe-Ullmann method was conducted in a commercial microwave oven in a few minutes at a low energy level and using erlenmeyer as adequate reaction vessels. Yields are similar to those obtained by conventional heating.
A new one-pot approach was developed to construct the 11H-indolo[3,2-c]quinoline scaffold through a gold-catalysed reaction of 2-[(2-aminophenyl)ethynyl]phenylamine derivatives with aldehydes. The broad scope and the high regioselectivity of this new protocol as well as the mild and neutral reaction conditions make it a viable alternative to the previously reported procedures.
