Abstract

At boiling in trifluoroacetic acid derivatives of 3-cyanovinyl-3-p-nitrophenylaminoindole are cyclized into the corresponding pyrido[3,2-b]indoles as a results of activation of the CN group. Thermal cyclization of ethyl indolylacrylate occurs with participation of the more reactive ethoxycarbonyl group to give 3-cyanopyrido[3,2-b]indole.
