Abstract

Résumé/Abstract In view of the contradictory results published in the literature concerning the structure of the indoloquinoxalines obtained by condensation of isatin with an unsymmetrical benzene-1, 2-diamine, regioselective syntheses of the 1-, 2-, 3-, and 4- aminoindolo [2, 3-b] quinoxalines have been developed. With the four derivatives in hand, isomers obtained by direct cyclocondensations starting from amino or nitro substituted ...
