15-Dimethyl-3-(3-phenyl-45-dihydro-12-oxazol-5-yl)meth­yl-1H-15-benzodiazepine-24(3H5H)-dione

摘要

The reaction of 3-allyl-1,5-dimethyl-1,5-benzodiazepine-2,4-dione and benzaldoxime leads to the title compound, C21H21N3O3. The mol­ecular structure is built up from two fused six- and seven-membered rings linked to a chain including a five- and six-membered ring (isoxazoline and phen­yl) via a methyl­ene group. The seven-membered ring displays a boat conformation. The dihedral angle between the two six-membered rings is 74.3 (1)°.
