5-(3-Chlorophenyl)-2-phenyl-3,4-dihydro-2H-pyrrole
In the title compound, C(16)H(14)ClN, the conformation of the five-membered ring approximates to an envelope with a C atom as the flap. The dihedral angle between the aromatic rings is 78.71 (9)°.
متن کامل2-ethoxycarbonyl-2-methyl-3,4-dihydro-2H-pyrrole-1-oxide: evaluation of the spin trapping properties.
The 2-ethoxycarbonyl-2-methyl-3,4-dihydro-2H-pyrrole-l-oxide (EMPO), an easily prepared pyrroline-N-oxide has been tested as a free radical scavenger. Spin adducts of superoxide, hydroxyl radical, and other free radicals were characterized in phosphate buffer at pH 7.0 and 5.6. At pH 7 in phosphate buffer, the EMPO/O(2)(-*) spin adduct was estimated to be about five times more persistent than i...
متن کامل(3R,4S)-3,4-Isopropylidenedioxy-3,4-dihydro-2H-pyrrole 1-oxide
The title compound C(7)H(11)NO(3) was prepared by intra-molecular nucleophilic displacement of 2,3-O-iso-propyl-idene-d-erythronolactol. There are two mol-ecules in the asymmetric unit, which are related by a pseudo-inversion centre. The crystal structure determination confirms unequivocally the configuration of the chiral centres as 3S,4R. In the crystal structure, inter-molecular C-H⋯O inter-...
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.
متن کامل1-(2-Nitrobenzyl)-1H-pyrrole-2-carbaldehyde
In the title compound, C(12)H(10)N(2)O(3), the five- and six-membered rings form a dihedral angle of 83.96 (6)°. The nitro group is twisted by 5.92 (8)° from the plane of the attached benzene ring. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into columns in the [100] direction, with a short distance of 3.725 (3) Å between the centroids of benzene rings inside t...
