Tetrazolo[1,5-alquinolines and 1,2,3-triazolo[1,5-alquinazolines by the action of cyano-carbanions on 2-azidoarylcarbonyl compounds

In protic solvents, 2-azidobenzaldehyde undergoes base-catalysed condensation with cyanocarbanions to yield tetrazolo[1,5-a]quinolines 5a-g, whereas in aprotic media 1,2,3-triazolo[1,5-a]quinazolines 6a-f are formed. Triazoloquinazolines 9 a-g are also ob
