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.
متن کاملEthyl 5-methyl-1H-pyrrole-2-carboxylate
In the title mol-ecule, C(8)H(11)NO(2), the r.m.s. deviation of non-H atoms from their best plane is 0.031 Å. Mol-ecules are connected via a pair of N-H⋯O hydrogen bonds into a centrosymmetric dimer.
متن کامل1-Benzyl-N-methyl-1H-pyrrole-2-carboxamide
The asymmetric unit of the title compound, C(13)H(14)N(2)O, contains two independent mol-ecules, which differ in the twist of the phenyl ring: the N(pyrrole)-C(H(2))-C-C torsion angles are -73.0 (3) and 17.1 (3)°. In the crystal structure, mol-ecules are linked through N-H⋯O hydrogen bonds into chains extending along the a axis.
متن کامل1H-Pyrrole-2-carbohydrazide
The title compound, C(5)H(7)N(3)O, was obtained by the reaction of ethyl 1H-pyrrol-2-carboxyl-ate and hydrazide hydrate. In the crystal, mol-ecules are linked via inter-molecular N-H⋯N and N-H⋯O hydrogen bonds, forming a supra-molecular grid.
