The gold-catalyzed reaction of o-phenylendiamine with propargylic alcohols affords 1,5-benzodiazepines bearing different substituents on the 2 and 4 positions. The method allows even for the selective preparation of 4-substituted 1,5-benzodiazepine derivatives.

A series of protic acidic ionic liquids have been used as solvents and catalysts for the synthesis of 1,5-benzodiazepines. Success of the condensation appears to lie in the choice of cation-anion combinations and the ionic liquid [HBIm]CF3SOsu

Under basic catalysis conditions the reaction of 4- and 4'-substituted chalcones with o-phenylenediamine leads to 2,3-dihydro-2,4-diaryl-1H-1,5-benzodiazepines; β-amino adducts, the ability of which to undergo intramolecular condensation increases as the
