Etude des voies d'accès aux aminométhyl benzo[g]isoquinoléinediones-5,10. Mise en évidence d'une substitution anormale au cours de la réaction de Bischler-Napieralski en série diméthoxy-1,4 naphthalène

Under the conditions of the Bischler-Napieralski reaction the cyclization of 2-(1,4-dimethoxy and 1,4,8-trimethoxynaphthyl)ethylacetamides derivatives take place essentially at the 1 position by substitution of the 1-methoxy group. Nevertheless, 1-aminomethyl-9,10-azaanthraquinones are accessibles by condensation of 1-aminomethylisoquinoline-5,8-diones with a 1,4-diacetoxy-1,3-butadiene.
