A new two-step route to chiral 3-substituted [1,4]benzo-diazepin-2-ones is described, which involves the coupling of 2-nitrobenzyl bromide with a series of aminoacids, followed by diazepine ring formation with Fe/AcOH at110 °C.

A series of 3-substituted1,4-benzodiazepin-2-ones derived from S and R amino acids were evaluated for their anti-ischemic activity in vitro. Treatment with compounds 7h, 16, 9d, and 17 decreased the apoptotic neuronal number, however increased the neuronal viability. The compounds decreasing apoptosis could protect neurons from the ischemic injury. The difference in the activities of 1,4-benzodiazepin-2-ones
