A new versatile synthesis of 6H-pyrido[4,3-b]carbazoles (ellipticines) is described which requires mild conditions and utilises easily accessible starting materials [indoles and 3-(1-chloroalkyl)pyridines]. It is illustrate the synthesis of 11-demethylellipticine, ellipticine, and 8,9-methylenedioxyellipticine. Overall yields comfavourably with those of previous syntheses.
