Abstract
The reaction of 2-azidobenzaldehydes with 2-thioamides of cyanoacetic acid proceeds without a solvent and base at 80–90°C selectively by one of the possible routes to form tetrazolo[1,5-a]quinolines. The proposed mechanism of the reaction involves the Knoevenagel condensation and subsequent intramolecular [3+2] cycloaddition of the azide group at the C≡N bond of an intermediate acrylonitrile.
