title: A practical synthesis of (S) 3-tert-butoxycarbonylamino-2-oxo-2,3,4,5-tetrahydro-1,5-benzodiazepine-1-acetic acid methyl ester as a conformationally restricted dipeptido-mimetic for caspase-1 (ICE) inhibitors.
abstract: A simple and versatile method for the synthesis of (S) 3-tert-butoxycarbonylamino-2-oxo-2,3,4,5-tetrahydro-1,5-benzodiazepine-1-acetic acid methyl ester (4), a dipeptide mimetic, has been developed. The regioselective functionalization of the N1 and N5 ring nitrogens and the C3 amino group is demonstrated in the synthesis of an interleukin-1beta converting enzyme inhibitor 13.
