Ethyl 5-(4-Bromophenyl)-4-methyl-1H-pyrrole- 2-carboxylate
This note describes a sequence converting an oxime-substituted pyrrolidine into a trisubstituted pyrrole structure. The synthetic route is based on a double chlorination of the pyrrolidine substrate followed by the base induced formation of both an imine and a nitrile oxide functionality. The latter reacts with an immobilized thiourea to yield an isothiocyanate which upon elimination generates ...
متن کاملMethyl 1H-pyrrole-2-carboxylate
The title compound, C(6)H(7)NO(2), is essentially planar with a dihedral angle of 3.6 (3)° between the pyrrole ring and the methoxy-carbonyl O/C/O/C plane. In the crystal structure, the N atom is a hydrogen-bond donor to the carboxylate C=O O atom of the neighboring mol-ecule. These inter-molecular hydrogen bonds lead to the formation of helical chains along the b axis.

In the title mol-ecule, C16H15NO, the tetra-hydro-pyridine ring is in a sofa conformation with the methine C atom forming the flap. The dihedral angle between the benzene rings is 80.85 (8)°. In the crystal, mol-ecules are arranged in alternating double layers parallel to (100) and are connected along [001] by N-H⋯O hydrogen bonds. In addition, weak C-H⋯π inter-actions are observed.
متن کاملMethyl 4-(trifluoromethyl)-1H-pyrrole-3-carboxylate
In the title compound, C7H6F3NO2, all the non-H atoms except for one of the F atoms lie on a crystallographic mirror plane. In the crystal, the mol-ecules are linked into inversion dimers by pairs of C-H⋯F inter-actions, forming R 2 (2)(10) loops. These dimers are connected into C(6) chains along [001] through N-H⋯O hydrogen bonds. Aromatic π-π stacking inter-actions [centroid-centroid separati...
متن کامل2-p-Tolyl-4,5-dihydro-1H-imidazole
In the mol-ecule of the title compound, C(10)H(12)N(2), the six- and five-membered rings are almost co-planar, forming a dihedral angle of 3.56 (8)°. In the crystal structure, neighbouring mol-ecules are linked together by inter-molecular N-H⋯N hydrogen bonds into one-dimensional infinite chains along the c axis. The crystal structure, is further stabilized by weak inter-molecular C-H⋯π and π-π...
