Synthesis of N1-(3-chloro-4-flourophenyl)-N4-sub­sti­tuted semicarbazones as novel anticonvul­sant agents

Several 3-chloro-4-flourophenyl substituted semicarbazones have been synthesized in three steps involving aryl urea and aryl semicarbazide formation. The structures have been confirmed by spectral and elemental analyses. Some selected compounds have been evaluated for anticonvulsant activity by using maximal electroshock seizure (MES) test. The compounds have also been screened for their neurotoxicity and CNS depressant activity.

Chemoselective hydrazine addition to diethyl 2-(2,3-dioxo-1,3-diarylpropyl)malonates and a tan­dem deesterification


The structural features of the product of the chemoselective reaction of hydrazine on only one of the ketones in a gem diester system with two keto groups by hydrazinium sulfate and hydrazine hydrate are described. A tandem deesterification has also been noticed during the reaction with hydrazine hydrate.

Synthesis and antibacterial properties of some novel 2-substituted-6-(4-methyl-6-substituted­cin­no­line-3-yl)imidazo[2,1-b][1,3,4]thiadiazoles


A series of 2-substituted-6-(4-methyl-6-substitutedcinnoline-3-yl)imidazo[2,1-b][1,3,4] thiadiazoles 5a-k have been synthe­sized by reacting 3-(2-bromoacetyl)-4-methyl-6-substituted­cinnolines 3 with various 2-amino-5-substituted-1,3,4-thia­diazoles 4 taking absolute ethanol as solvent. The structures of the newly synthesized compounds have been characterized by elemental analysis, IR, 1H NMR spectral data. All the newly synthesized compounds have been tested for their antibacterial properties against gram-positive and gram-negative bacteria.

Microwave-assisted zeolite catalyzed Claisen rearrangement of allyl aryl ethers under solvent-free conditions


Claisen rearrangement of allyl aryl ethers has been studied extensively over various zeolites under microwave activation and solvent free conditions at 80°C. Hβ-zeolite is found to be an efficient catalyst for the rearrangement. The reaction gives o-rearranged product selectively instead of expected further cyclized dihydrobenzofuran derivative.

Recombination of propargyl radicals to form benzene: A computational study


Present study involves QCISD(T)/6-311G(d,p) level calculations to analyze reaction pathways during the recombination of propargyl radicals leading to the formation of benzene. Geometries of all the species are optimized at HF/6-31G(d) level. Intrinsic Reaction Coordinate (IRC) calculation has been performed in order to ascertain the existence of the transition states.
