(4Z)-4-(2-Oxo-propyl--idene)-1,3-bis--(prop-2-en-1-yl)-2,3,4,5-tetra-hydro-1H-1,5-benzodiazepin-2-one

摘要

In the title compound, C18H20N2O2, the diazepin-2-one ring adopts a tub conformation. The conformation of the acetyl group is partially determined by an intramolecular N—HO hydrogen bond. In the crystal, pairwise C—HO hydrogen bonds form inversion dimers.
