title: 2-Hydr-oxy-10-phenacyl-pyrrolo[2,1-c][1,4]benzodiazepine-5,11-dione.
abstract: The title compound, C(20)H(18)N(2)O(4), consists of a benzodiazepinedione system fused to a pyrrole system. The seven-membered ring adopts a boat-shaped conformation (with the methine C atom as the prow); the five-membered ring adopts an enveloped-shaped conformation (with the hydr-oxy-bearing C atom as the flap). In the crystal, the hydr-oxy group is hydrogen bonded to the carbonyl O atom of an adjacent mol-ecule, generating a zigzag chain.
