A new entry to the preparation of pyrrolo[2,3-b]quinolines by an aza Wittig/electrocyclic ring-closure/nitrene insertion process

A new method for the preparation of the pyrrolo[2,3-b]quinoline ring system involving the sequential formation of the pyridine ring (elcctrocyclic ring-closure) and the pyrrole (nitrene insertion reaction) rings. This approach is based on the regioselective formation of the iminophosphorane 2 from the bis(azide) 1, followed by aza Wittig reaction with isocyanates and further thermal treatment.

Pyrroloquinolines: Part IV - Synthesis of 1-Aryl-1H-pyrroloquinolines

A wide variety of 1-aryl-2-chloro-1H-pyrroloquinolines (3) have been synthesized by cyclocondensation of 2-quinolone-3-acetanilides (2) with phosphoryl chloride.The chloropyrroloquinolines on hydrogenolysis afford the corresponding pyrroloquinoline
