N-para-sulfonium salt substituted pyrazoline derivative, photocurable composition and preparation method

The invention relates to an N-para-sulfonium salt substituted pyrazoline derivative shown as the following formula (I) in the specification, a photocurable composition, and a preparation method of theN-para-sulfonium salt substituted pyrazoline derivative shown as the following formula (I). The N-para-sulfonium salt substituted pyrazoline derivative shown as formula (I) has good absorption at a wavelength of 350nm or above, and compared with a 5-substituted sulfonium salt, the N-para-sulfonium salt substituted pyrazoline derivative has the advantages of simpler and more convenient molecule synthesis steps and reduced cost of raw materials, and is more suitable for industrial production and application.

Electrochemical 1,4-reduction of α,β-unsaturated ketones with methanol and ammonium chloride as hydrogen sources

A sustainable, chemoselective 1,4-reduction of α,β-unsaturated ketones by means of an electrochemical method is presented, wherein the extremely inexpensive ammonium chloride (NH4Cl) is applied as the only additive. The reaction proceeds smoothly in the air at ambient temperature. Mechanistic studies reveal that both NH4Cl and solvent methanol work as hydrogen donors.

Iron-Catalyzed Chemoselective Reduction of α,β-Unsaturated Ketones

An iron-catalyzed chemo- and diastereoselective reduction of α,β-unsaturated ketones into the corresponding saturated ketones in mild reaction conditions is reported herein. DFT calculations and experimental work underline that transfer hydride reduction is a more facile process than hydrogenation, unveiling the fundamental role of the base.

A new solid acid catalyst FeCl3/bentonite for aldol condensation under solvent-free condition

For the first time, a new solid acid catalyst has been used for the synthesis of aryl chalcones under solvent free conditions. A simple method (solid dispersion method) has been adopted for the synthesis of FeCl3/bentonite. The prepared catalyst has been characterized by different characterization techniques. A series of E-1-(substituted phenyl)-3-(1-pyrenyl)-2-propen-1-ones have been synthesized using FeCl3/bentonite under microwave-assisted solvent-free conditions. The yields are in the range from 80 to 88%. All the synthesized chalcones have been characterized by their physical constants, analytical, IR, 1H and 13C NMR spectral data. This catalyst can be reused for further runs (after fifth cycle) without decrease in activity. This catalyst gives excellent yields and is inexpensive and easily recyclable for this reaction.

Synthesis and biological evaluation of naphthalene, furan and pyrrole based chalcones as cytotoxic and antimicrobial agents

Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are collectively known as chalcones. These show antibacterial, antifungal, antitumour and antiinflammatory properties, and also are intermediates in the biosynthesis of flavonoids, substances widespread in plants with an array of biological activities. These biaryl propenones show potent toxicity to several cancer cell lines and interact with tubulin at its colchicine-binding site. Tubulin binding molecules interfere with the dynamic instability of microtubules and thereby disrupt microtubule inducing cell cycle arrest in the M phase, forming abnormal spindles and finally leading to apoptotic cell death. Basically Chalcones consists of C6-C3-C6 units but in the present study we report the reactions of 1-acetylnaphthalene, 2-acetylfuran and 2-acetylpyrrole with aldehydes, thus getting compounds akin to chalcones. 31 analogues have been synthesised and evaluated for cytotoxic potential against PC-3, OVCAR, IMR-32 and HEP-2. Compound 9 was found to be the most cytotoxic with inhibition ranging from 72 to 88% against the cell lines employed. The synthetics were also evaluated for antimicrobial activity and compound 25 was found to be the most potent. Springer Science+Business Media, LLC 2011.

Synthesis and selective inhibitory activity against human COX-1 of novel 1-(4-substituted-thiazol-2-yl)-3,5-di(hetero)aryl-pyrazoline derivatives

Novel 1-(4-ethyl carboxylate-thiazol-2-yl)-3,5-di(hetero)aryl-2-pyrazoline derivatives were obtained by reacting 3,5-di(hetero)aryl-1-thiocarbamoyl-2- pyrazolines with the ethyl ester of α-bromo-pyruvic acid. The synthesized compounds were confirmed by spectroscopic data and assayed to evaluate their in vitro ability to inhibit both isoforms of human cyclooxygenase (hCOX). Some derivatives (compounds 5, 6, 13, 16, and 17) displayed promising selectivity against hCOX-1 in the micromolar range and were shown to have a selectivity index similar or better than the reference drugs (indometacin, diclofenac). The introduction of a phenyl or a 4-F-phenyl ring on the C5 associated with a 4-substituted phenyl or a heteroaryl group on the C3 of (4-substituted-thiazol- 2-yl)pyrazoline derivatives improved the activity against hCOX-1. Thanks to these preliminary results it could be possible to extend our knowledge of the pharmacophoric requirements for the discovery of new pyrazoline-based hCOX-1 inhibitors. Novel 1-(4-ethyl carboxylate-thiazol-2-yl)-3,5-di(hetero)aryl-2- pyrazoline derivatives were obtained by reacting 3,5-di(hetero)aryl-1- thiocarbamoyl-2-pyrazolines with the ethyl ester of α-bromo-pyruvic acid. Some derivatives displayed promising selectivity against human cyclooxygenase 1 (hCOX-1) in the micromolar range, with a selectivity index similar or better than the reference drugs, indometacin and diclofenac.
