Synthesis and Bioactivity of 5-Aryl-4-acyl-3-hydroxy-1-[2-(imidazolyl-3-yl)ethyl]3-Pyrroline-2-ones
Russian Journal of General Chemistry, 2020Co-Authors: V. L. Gein, N. N. Kasimova, S. V. Chaschina, A. V. Starkova, A. N. YankinAbstract:5-Aryl-4-acyl-3-hydroxy-1-[2-(imidazolyl-3-yl)ethyl]-3-Pyrroline-2-ones were synthesized by three-component reaction of methyl dioxobutanoates with aromatic aldehydes and histamine dihydrochloride. Analgesic activity and hemostatic action of some compounds obtained was investigated.

4,4′,4”-(Methane-triyl)triphenyl tris-(2,2,5,5-tetra-methyl-1-oxyl-3-Pyrroline-3-carboxyl-ate) benzene tris-olvate.
Acta Crystallographica Section E Structure Reports Online, 2010Co-Authors: Denise Schuetz, Dominik Margraf, Thomas F. Prisner, Jan W. BatsAbstract:In the asymmetric unit of the title compound, C46H52N3O9·3C6H6, two of the benzene solvent molecules are located in general positions and two are disposed about inversion centers. One of the benzene molecules on an inversion center was grossly disordered and was excluded using the SQUEEZE subroutine in PLATON [Spek (2009). Acta Cryst. D65, 148–155]. In addition, one of the 2,2,5,5-tetramethyl-1-oxyl-3-pyrrolin-3-ylcarbonyl groups is disordered over two orientations with refined occupancies of 0.506 (2) and 0.494 (2). The 1-oxyl-3-Pyrroline-3-carboxylate groups are essentially planar, with mean deviations from the planes of 0.026 (2), 0.012 (2), 0.034 (4) and 0.011 (4) A. In the crystal structure, molecules are connected by five weak intermolecular C—H⋯O and four weak intermolecular C—H⋯π(benzene) interactions.

Biphenyl-4,4′-diyl bis-(2,2,5,5-tetra-methyl-1-oxyl-3-Pyrroline-3-carboxyl-ate).
Acta Crystallographica Section E Structure Reports Online, 2009Co-Authors: Dominik Margraf, Denise Schuetz, Thomas F. Prisner, Jan W. BatsAbstract:In the title compound, C30H34N2O6, the complete molecule is generated by a crystallographic 2/m symmetry operation. The 1-oxyl-3-Pyrroline-3-carboxylate group lies on a mirror plane. The dihedral angle between the ring planes of the biphenyl fragment is constrained by symmetry to be zero, resulting in rather short intramolecular H⋯H contact distances of 2.02 A. In the crystal, molecules are connected along the a-axis direction by very weak intermolecular methyl–phenyl C—H⋯π interactions. The C—H bond is not directed to the center of the benzene ring, but mainly to one C atom [C—H⋯C(x − 1, y, z): H⋯C = 2.91 A and C—H⋯C = 143°].
