SYNTHESIS AND ANTIBACTERIAL AND ANALGESIC ACTIVITY OF 5-ARYL-4-ACYL-3-HYDROXY-1(2,2-DIMETHOXYETHYL)-3-PYRROLIN-2-ONES

5-Aryl-4-acyl-3-hydroxy-1-(2,2-dimethoxyethyl)-3-pyrrolin-2-ones were synthesized by the reaction of acylpyruvic acid methyl esters with a mixture of an aromatic aldehyde and aminoacetaldehyde dimethylacetal. The proposed structures are confirmed by IR and PMR spectroscopy. The results of an investigation of the antibacterial and analgesic activity of the synthesized compounds are presented.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 29331-92-8, in my other articles.

Palladium-Catalyzed Intermolecular Oxidative Cyclization of Allyltosylamides with AcOH: Assembly of 3-Pyrrolin-2-ones

The first example of Pd-catalyzed oxidative cyclization of allyltosylamides with acetic acid is reported. This transformation involved C-N/C-C bond formation and provided 3-pyrrolin-2-ones in a one-pot manner with easy-operation, excellent atom economy and good yields. Mechanistic studies indicate that the reaction proceeds through intermolecular aminopalladation, migratory insertion, reinsertion and beta-hydride elimination processes.

Investigation of conjugated dinitrones – Derivatives of pyrroline oxide

The molecular structure of three derivatives of bis(2-R-5,5-dimethyl-3-oxo-1-oxide pyrrolin-1-ylidene-3), where R = CH3 (5a), C6H5 (5b), C(CH3)(3) (5c), and of the complex of 5b with copper(II) hexafluoroacetylacetonate [Cu(hfac)(2) (5b)] was investigated by X-ray diffraction analysis in the framework of our studies of the possible tautomeric equilibrium conjugated dinitrone nitroxide biradical. The pyrroline rings of the molecules under analysis are planar (rms deviations of atoms are no more than 0.041 Angstrom), and the interplanar angles are 32.01(5), 42.84(9), and 51.45(7)degrees for 5a, 5b, and 5c, respectively. It is established that the bond lengths of the C(2)-C(3)=C(3a)-C(2a) fragment are equalized to C(2)-C(3) 1.42 and C(3)-C(3a) 1.40 Angstrom. The N–>O bond lengths of the nitrone group are within 1.250(4)-1.282(4) Angstrom [in Cu(hfac)2 (5b)]. The geometrical data obtained do not permit us to make an unambiguous choice between the tautomeric structures. The magnetic susceptibility measurements of the Cu(hfac)2 solid complex (5b) and the absence of paramagnetism in solid compounds 5 indicate that they are diamagnetic.

Synthesis and characterization of a crosslinked membrane based on sulfonated poly(aryl ether sulfone) and sulfonated polyvinyl alcohol applied in direct methanol fuel cells

Vinyl-terminated sulfonated poly (arylene ether sulfone) (VSPAES) and sulfonated polyvinyl alcohol containing vinyl group (VSPVA) have been prepared. The VSPVA and VSPAES were crosslinked by adding AIBN as initiator. The results of FT-IR and H-1-NMR indicated the existence of sulfonic acid groups and crosslinked structure in these crosslinked membranes. The microphase structures of the membranes are analyzed by SEM. The proton conductivities of membranes were above 10 mS cm(-1), which indicated that it basically meet the needs of fuel cells. The methanol permeability coefficients of CSPAES membrane is 2.8×10(-7) cm(2) s(-1), remarkably lower than neat SPAES (8.5×10(-7) cm(2) s(-1)) and Nafion117 (14.1×10(-7) cm(2) s(-1)). Moreover, the proton selecticity of CSPAES membrane is close to 2 times higher than that of Nafion 117 membrane. The crosslinked membrane showed better stability than the linear SPAES membrane.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 56353-15-2 is helpful to your research. Category: pyrrolines.
