NOUVELLE VOIE DE SYNTHESE D'ARYLPYRAZOLO - - QUINOLEINES VIA LA CYCLOADDITION DIPOLAIRE -1,3

The regiospecificity of the diarylnitrilimines (D.A.N.I) action on the heterocycles such as the benzofuranne and N-methylindole has been demonstrated spectroscopically and chemically.With the N-alkylindoles having an alkoxycarbonyle function in the positi

Regiospecificite de la cycloaddition des diarylnitrilimines sur quelques derives indoliques

In this paper, we describe the results of a study of the reaction of diaryl nitrilimines with N-ethylindole (1) and 2-methoxycarbonyl-N-ethylindole (2).The regioselectivity of the reaction is reversed when going from 1 to 2 as it has been spectroscopically and chemically demonstrated.
