2-Hydroxy-10-phenacylpyrrolo[2,1-c][1,4]benzodiazepine-5,11-dione
The title compound, C20H18N2O4, 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 hydroxy-bearing C atom as the flap). In the crystal, the hydroxy group is hydrogen bonded to the carbonyl O atom of an adjacent molecule, generating a zigzag chain
2-Hydroxy-10-propargylpyrrolo[2,1-c][1,4]benzodiazepine-5,11-dione monohydrate
The title compound, C15H14N2O3·H2O, 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 hydroxy-bearing C atom as the flap). In the crystal, adjacent molecules are linked by O—H⋯O hydrogen bonds into sheets parallel to (102). In addition, Cacetylinic—H⋯O hydrogen bonds occur
