A new approach to the construction of tricyclic 1,4-benzodiazepines has been developed, based upon the intramolecular Diels-Alder (IMDA)reaction of 2-cyano-l-azadienes. This study revealed the difficulties inherent to the direct transformation of imine-amide 2 to azadiene 3, but demonstrated the eff
