Abstract
Three different synthetic routes to substituted 2,3′-diindolylmethanes, and the syntheses
of substituted indolo[3,2-b ]carbazoles are described. The first rigid proof of an acylation in the 2-position
of a 1,3-unsubstituted indole is also presented in the form of an X-ray structure.
Key words
bisindoles - acylations - Lewis acids - aryl hydrocarbon receptor - indolo[3,2-b ]carbazole
