A simple, straightforward and efficient synthesis of 6H‐indolo[2,3‐b]quinoline, a natural product isolated from leaves of Justicia betonica, is achieved through a pivalic acid‐assisted one‐pot alkylation–dehydration–cyclization–aromatization approach. This synthesis constitutes a formal approach toward a biologically important alkaloid neocryptolepine.

A new two-step approach for the synthesis of 6H-indolo[2,3-b]quinolines is described using indole C3 alkylation and a one-pot reduction-cyclization-aromatization sequence. The synthesis of the parent 6H-indolo[2,3-b] quinoline system constitutes a formal synthesis of the alkaloid neocryptolepine (cryptotackieine).
