ACCES AUX DINITRO-2,4 DIARYLAMINES PAR SUBSTITUTION NUCLEOPHILE SNAr-LIMITES DE LA REACTION ET APPLICATION A LA SYNTHESE DE CYANOCARBAZOLES
3-Cyanocarbazoles, key-intermediates in the total synthesis of pyrido carbazoles, have been obtained starting from easily available materials and involving the cyclization of diarylamines.The first step of the preparation consists in a SNAr reaction between a para substituted aniline and a chloro- (or bromo)-dinitrobenzene.This nucleophilic substitution has been found to be hindered by the steric effect of a methyl group, explained in terms of inhibition of resonance and confirmed by X-ray determination.
