Abstract

A 1:1 epimeric mixture of 2(R,S)-(4-nitro­phen­yl)-3-[(4-nitro­benzyl­idene)amino]-5(S)-(propan-2-yl)imidazolidin-4-one was derived from an initial reaction of 2(S)-amino-3-methyl-1-oxo­butane­hydrazine at its hydrazine moiety to provide a 4-nitro­benzyl­idine derivative, followed by a cyclization reaction with another mol­ecule of 4-nitro­benzaldehyde to form the chiral five-membered imidazolidin-4-one ring.
