A method of synthesis of pyrrolo[1,2-a][1,4]benzodiazepines is described. This method is based on the recyclization of N-(furfuryl)anthranilamides under treatment with an aq. HCl/AcOH system and allows one to form both diazepine and pyrrole rings in one step. The reaction proceeds via furan ring opening into a diketone moiety followed by consecutive interaction of the NH(2)-group with both carb...

Pre-organised tricarboxylate ligands based on 6-amino-perhydro-1,4-diazepine bind (68)Ga rapidly and selectively in acetate buffer at pH 4 to 7, forming kinetically stable complexes suitable for use in PET imaging.

The title compound, C21H19N3O, exhibits an E configuration with respect to the C=C bond between the benzodiazepine and tri-methyl-amine groups. The seven-membered diazepine ring displays a boat conformation. In the crystal, mol-ecules are linked by a C-H⋯O hydrogen bond, forming a chain along [110].

The asymmetric unit of the title compound, C(14)H(14)N(2)O(2), comprises two independent mol-ecules, which slightly differ in the orientation of the propargyl chain. In both molecules, the diazepine ring adopts a boat conformation with the propargyl-bearing C atom as the prow and the C atoms at the ring junction as the stern. The carbonyl O atom of one independent mol-ecule is hydrogen bonded t...

a series of curcumin derivatives containing heterocyclic moiety have been synthesized and evaluated for their antibacterial activities. the chemical structures of the synthesized compounds were verified on the basis of spectral data and elemental analyses. investigation of antimicrobial activity of the derivatives demonstrated the ability to inhibit gram-positive microorganisms with zone of inh...

In the title compound, C(20)H(15)N(3)O, the diazepine ring adopts a boat conformation. The dihedral angle between pyridine and benzene rings is 55.2 (1)°. The benzoyl phenyl ring forms dihedral angles of 49.4 (1) and 75.9 (1)°, respectively, with the pyridine and benzene rings. In the crystal, mol-ecules are linked into centrosymmetric dimers by pairs of C-H⋯N hydrogen bonds.

BACKGROUND 1,4-Diazepine derivatives are the seven membered, nitrogen containing heterocyclic ring systems possessing a wide range of therapeutic applications. 1,4-Diazepines attracted the attention of chemists and druggists due to their biological and medicinal properties, such as antimicrobial, anti-HIV and anticancer activities. Herein, we report the preparation, crystal structure determined...

The title compound, C(18)H(15)ClN(2)O(2), is a potential human immunodeficiency virus type-1 (HIV-1) non-nucleoside reverse transcriptase inhibitor. The pyrrolidine ring adopts an envelope and the diazepine ring a boat conformation. In the crystal structure, two isomers (R and S) form centrosymmetric dimers via N-H⋯O hydrogen bonds.

The title compound, C(17)H(22)N(4)O(3), comprises a 1,4-diazepine ring in a twist-boat conformation fused to a pyrimidine ring. The dihedral angle between the pyrimidine and phenyl rings is 80.8 (1)°. The crystal packing features N-H⋯O and C-H⋯O hydrogen bonds.

The title compound, C(25)H(23)N(3)O, features a benzene ring fused with a seven-membered 1,4-diazepine ring; the latter ring adopts a boat conformation with the (dimethyl-amino)methyl-bearing C atom as the prow and the fused-ring C atoms as the stern. There are two independent mol-ecules in the asymmetric unit with similar conformations.
