10-Allyl-2,3-dihydro-1H-pyrrolo[2,1-c][1,4]benzodiazepine-5,11(10H,11aH)-dione.

ABSTRACT: The compound, C(15)H(16)N(2)O(2), features a pyrroline ring fused with a seven-membered diazepine ring; the latter system adopts a boat conformation (with the methine C atom as the prow and the two C atoms of the aromatic ring as the stern). A CH(2)-CH(2) segment of the pyrroline ring is disordered over two positions in a 1:1 ratio.

Project description:In the two mol-ecules of the asymmetric unit of the title compound, C(12)H(11)N(3)O(4), the seven-membered diazepine ring adopts a boat conformation (with the two phenyl-ene C atoms representing the stern and the methine C atom the prow). The five-membered pyrrole ring, which has an envelope conformation, makes dihedral angles of 60.47?(10) and 54.69?(9)° with the benzene ring of the benzodiazepine unit in the two mol-ecules. In the crystal, inter-molecular N-H?O hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distance = 3.8023?(7)-3.8946?(7)?Å] lead to the formation of a three-dimensional framework.

Project description:The seven-membered ring of the title compound, C(12)H(12)N(2)O(3), which is fused with the phenyl-ene ring, adopts a boat-shaped conformation (with the methine C atom as the prow and the phenyl-ene C atoms as the stern); the H atom on the methine linkage exists in an axial position.

The two independent mol-ecules are disposed about a pseudo center of inversion and are connected by a pair of N-H?O hydrogen bonds. Adjacent dimers are linked by a pair of O-H?O hydrogen bonds, generating a chain running along the b axis.

Crystal structure, Hirshfeld surface analysis and inter-action energy and DFT studies of (S)-10-propargyl-pyrrolo-[2,1-c][1,4]benzodiazepine-5,11-dione.

Project description:The title compound, C15H14N2O2, consists of pyrrole and benzodiazepine units linked to a propargyl moiety, where the pyrrole and diazepine rings adopt half-chair and boat conformations, respectively. The absolute configuration was assigned on the the basis of l-proline, which was used in the synthesis of benzodiazepine. In the crystal, weak C-HBnz?ODiazp and C-HProprg?ODiazp (Bnz = benzene, Diazp = diazepine and Proprg = proparg-yl) hydrogen bonds link the mol-ecules into two-dimensional networks parallel to the bc plane, enclosing R 4 4(28) ring motifs, with the networks forming oblique stacks along the a-axis direction. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H?H (49.8%), H?C/C?H (25.7%) and H?O/O?H (20.1%) inter-actions. Hydrogen bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Computational chemistry indicates that in the crystal, C-H?O hydrogen-bond energies are 38.8 (for C-HBnz?ODiazp) and 27.1 (for C-HProprg?ODiazp) kJ?mol-1. Density functional theory (DFT) optimized structures at the B3LYP/6-311?G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap.

(11aS)-7-Bromo-2,3,5,10,11,11a-hexa-hydro-1H-pyrrolo-[2,1-c][1,4]benzodiazepine-3,11-dione.

Project description:The title compound, C(12)H(11)BrN(2)O(2), was prepared by an intra-cyclization reaction of (S)-1-(5-bromo-2-nitro-benz-yl)-5-oxopyrrolidine-2-carb-oxy-lic acid methyl ester in the presence of EtOH/Fe. The five-membered pyrrolidinone ring adopts an approximate envelope conformation, while the seven-membered diazepanone ring displays a twisted boat conformation. Inter-molecular classical N-H?O hydrogen bonds and weak C-H?O inter-actions help to stabilize the crystal structure.
