NEW ASPECTS OF THE CHEMISTRY OF 2,3-DIHYDRO-1H-1,5-BENZODIAZEPINE
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; beta-amino adducts, the ability of which to undergo intramolecular condensation increases as the basicity of the catalyst is increased, are formed as intermediates.A different pathway for the process (the formation of an azomethine) is observed in the reaction with cinnamaldehyde.It is concluded that conformational factors play a primary role in the direction of the reaction.
