1,4-benzodiazepin-2,5-diones have been synthesized in good overall yields by two routes, the first one by cyclisation of dipeptides prepared from Boc anthranilic acid and α-amino acid methyl esters, the second one by reaction of N-carboxy α-amino acid anhydrides with Boc anthranilic acid.

Reaction of isatoic anhydrides (1) and α-amino acids (2) in glacial acetic acid under reflux gave 3H-1(H),4(H)-benzodiazepin-2,5-diones (3) in good yields.These compounds have been characterised by UV, IR, mass, PMR and 13C-NMR spectra.
