(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 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 کامل5-(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 کامل(3R,4S)-3,4-Isopropylidenedioxy-5-phenylsulfonylmethyl-3,4-dihydro-2H-pyrrole 1-oxide
The title compound, C(14)H(17)NO(5)S, was prepared by oxidation of (2R,3S,4R)-2-phenyl-sulfonyl-methyl-1-hy-droxy-3,4-iso-pro-pyl-idene-dioxy-pyrrolidine. Its crystal structure confirms unequivocally its configuration. Two inter-molecular C-H⋯O inter-actions help to establish the packing.
متن کاملDimethyl 4-ethoxy-1-(4-methyl-2-pyridyl)-5-oxo-2,5-dihydro-1H-pyrrole-2,3-dicarboxylate
In the title compound, C(16)H(18)N(2)O(6), the dihedral angle between the aromatic ring planes is 8.11 (6)°. One of the O atoms is disordered over two sites of equal occupancy. In the crystal structure, aromatic π-π stacking [centroid-to-centroid separation = 3.5503 (8) Å] helps to consolidate the packing.
