reflux in acetic acid, these compounds were acetylated to give the cinnoline derivatives 9. The pyrazolones 10a, b react with 3‐furfurylidene‐ and 3‐thienylidene‐malononitrile derivatives 11a, b to afford the pyrano[2,3‐c]pyrazolederivatives 13a–d. These newly synthesized compounds show generally a moderate molluscicidalactivity to Biomphalaria alexandrina snails.

A one-stage procedure was developed for preparing new partially hydrogenated derivatives of benzoacridine and benzophenanthroline. The procedure was a triple condensation of 6-aminoquinoline or 2-naphthylamine with formaldehyde and hydroxycyclohexylidenepropanedinitriles, functionalized analogs of cyclic beta-diketones.
