Reactions of 4-Cyanobenzo-[c]pyrylium salts with Nitrogen-containing nucleophiles

The recyclization reactions of 4-cyanobenzo[c]pyrylium salts with ammonia, primary amines, and hydrazines have been studied. New derivatives of isoquinoline, benzo-2,3-diazepine, and pyrazolo-[ 5,4-c]isoquinoline have been obtained.

SYNTHESIS OF AZOLOISOQUINOLINES

Two pathways are presented for the synthesis of pyrazoloisoquinoline derivatives: recyclization of 1-methyl-3-phenyl-4-cyano-6,7-dimethoxybenzopyrylium perchlorate upon treatment with hydrazine, and Bischler-Napieralski cyclization of substitute
