چکیده
The title compound, C16H17NOS2, consists of a carbazole skeleton with methyl and dithiol-ane groups as substituents. In the indole ring system, the benzene and pyrrole rings are nearly coplanar, forming a dihedral angle of 1.02 (11)°. The cyclo-hexenone ring has a twisted conformation, while the dithiol-ane ring adopts an envelope conformation with one of the CH2 C atoms at the flap. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into supra-molecular chains nearly parallel to the c axis. These hydrogen bonds together with weak C-H⋯π inter-actions link the molecules into a three-dimensional supramolecular network.

The title compound, C(22)H(17)N(3)O(4), was prepared through 1,3-dipolar cyclo-addition: the dihedral angle between the benzimidazole and benzene rings is 80.93 (6)°. The crystal structure is stabilized by weak π-π inter-actions between the planar pyrrolobenzimidazole rings (r.m.s. deviation = 0.0293 Å) of neighbouring mol-ecules, forming chains along the c axis. The perpendicular distance is 3...

متن کاملBase Catalyzed Synthesis of Novel Fused-Imidazoles from N-Vinyl-1H-imidazole
Syntheses of various classes of fused-imidazoles are reported. The key to their successful synthesis depends on the reaction of N-vinyl-1H-imidazole with the π-deficient compounds under basic conditions. Reaction of the target imidazole with 1,1,2,2-tetracyanoethylene and dimethyl acetylenedicarboxylate afforded pyrrolo[1,2-a]imidazoles. On the other site, reaction of the target imidazole with ...
