An electrochemical alternative approach to the cyclization of alkynes bearing proximate malonyl moieties

A versatile alternative approach to the synthesis of butenolides, quinolones and 3-pyrrolin-2-ones has been achieved by galvanostatic electrolysis of MeCN/TEATFB solutions and subsequent addition of the cathodic solution to alkynes bearing proximate malonyl moieties. The electrogenerated cyanomethyl anion permits the formation of the reactive anionic intermediates under mild conditions, avoiding the need to use classical bases. ((C) Wiley-VCH Verlag GmbH & Co.

ZG-1494 alpha, a novel platelet-activating factor acetyltransferase inhibitor from Penicilium rubrum, isolation, structure elucidation and biological activity

A novel inhibitor of platelet-activating factor (PAF) acetyltransferase, an essential enzyme in the remodeling pathway of platelet-activating factor synthesis, was identified by a high throughput screen of natural product extracts of microbial origin. The compound, ZG-1494 alpha, was isolated from an ethyl acetate extract of a culture broth of Penicillium rubrum through bioassay guided fractionation. The structure of ZG-1494 alpha was determined by spectroscopic methods. A key feature of the structure, which is relatively rare among natural products, is the 5-hydroxy-3-pyrrolin-2-one moiety. A C-13-C-13 INADEQUATE was utilized to unambiguously determine the regiochemistry of this molecule.

A Comparison Study on Reinforcement Behaviors of Functional Fillers in Nitrile Rubber Composites

To investigate the reinforcing effects of functional fillers in nitrile rubber (NBR) materials, high-structure carbon black (HS45), coated calcium carbonate (C-CaCO3), silica (200MP), and multi-walled carbon nanotubes (MWCNTs) were used as functional filler, and carbon black (SRF) as a common filler were used for oil-resistant rubber. The curing and mechanical properties of HS45-, 200MP-, and MWCNT-filled NBR compounds were improved compared to those of the SRF-filled NBR compound. The reinforcing effect also increased with a decrease in the particle size of the fillers. The C-CaCO3-filled NBR compound exhibited no reinforcing effect with increasing filler concentration because of their large primary particle size (2 mu m). The reinforcing behavior based on 100% modulus of the functional filler based NBR compounds was compared by using several predictive equation models. The reinforcing behavior of the C-CaCO3-filled NBR compound was in accordance with the Smallwood-Einstein equation whereas the 200MP- and MWCNT-filled NBR compounds fitted well with the modified Guth-Gold (m-Guth-Gold) equation. The SRF- and HS45-filled NBR compounds exhibited reinforcing behavior in accordance with the Guth-Gold and m-Guth-Gold equations, respectively, at a low filler content. However, the values of reinforcement parameter (100M(f)/100M(u)) of the SRF- and HS45-filled NBR compounds were higher than those determined by the predictive equation model at a high filler content. Because the chains of SRF composed of spherical filler particles are similarly changed to rod-like filler particles embedded in a rubber matrix and the reinforcement parameter rapidly increased with a high content of HS45, the higher-structured filler. The reinforcing effectiveness of the functional fillers was numerically evaluated on the basis of the effectiveness index (phi(SRF)/phi(f)) determined by the ratio of the volume fraction of the functional filler (phi(f)) to that of the SRF filler (phi(SRF)) at three unit of reinforcing parameter (100M(f)/100M(u)). On the basis of their effectiveness index, MWCNT-, 200MP-, and HS45-filled compounds showed higher reinforcing effectiveness of 420%, 70%, and 20% than that of SRF-filled compound, respectively whereas C-CaCO3-filled compound exhibited lower reinforcing effectiveness of -50% than that of SRF-filled compound.

Z-Selective alpha-Arylation of alpha,beta-Unsaturated Nitriles via [3,3]-Sigmatropic Rearrangement

The Morita-Baylis-Hillman (MBH) reaction and [3, 3]-sigmatropic rearrangement are two paradigms in organic synthesis. We have merged the two types of reactions to achieve [3,3]-rearrangement of aryl sulfoxides with alpha,beta-unsaturated nitriles. The reaction was achieved by sequentially treating both coupling partners with electrophilic activator (Tf2O) and base, offering an effective approach to prepare synthetically versatile alpha-aryl alpha,beta-unsaturated nitriles with Z-selectivity through direct alpha-C-H arylation of unmodified alpha,beta-unsaturated nitriles. The control experiments and DFT calculations support a four-stage reaction sequence, including the assembly of Tf2O activated aryl sulfoxide with alpha,beta-unsaturated nitrile, MBH-like Lewis base addition, [3,3]-rearrangement, and E1cB-elimination. Among these stages, the Lewis base addition is diastereoselective and E1cB-elimination is cis-selective, which could account for the remarkable Z-selectivity of the reaction.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 95-45-4, you can contact me at any time and look forward to more communication. HPLC of Formula: https://www.ambeed.com/products/95-45-4.html.

Concise Synthesis of 3-(Aminomethyl)pyrrolizidines via an In(OTf)(3)-Mediated Ring Rearrangement of 2-[2-(1-Pyrrolin-2-yl)alkyl]aziridines

In this study, an efficient ring rearrangement of 2-[2-(1-pyrrolin-2-yl)alkyl]aziridines, prepared from 2-(bromomethyl) aziridines, toward novel trans-and cis-3-aminomethyl-substituted pyrrolizidines was developed. To that end, addition of In(OTf)(3) as an appropriate Lewis acid catalyst resulted in the formation of intermediate pyrrolizidinium salts via regioselective aziridine ring opening, which were then trapped by a hydride or cyanide nucleophile. Column chromatographic purification allowed the isolation of the major trans-isomers, exclusively.

Synthesis, molecular modeling and biological evaluations of novel pyrrolidine derivatives as potential cyclooxygenase-2 (COX-2) inhibitors

Toward the development of selective cyclooxygenase-2 inhibitors, a series of pyrrolidine derivatives is described. All the compounds containing sulfonamide, ester, nitrile, acid, amide and urea functionalities were computationally screened, and binding affinity scores for all synthesized compounds with cyclooxygenase-1 and cyclooxygenase -2 were compared. The computational observations showed three top-ranked compounds (8b, 8d and 10a) having selectively more affinity for cyclooxygenase -2. These were selected for pharmacological evaluation using carrageenan-induced rat paw edema model. Compound 8b showed maximum activity (54.83%) which was closer to standard drug indometacin (57.48%). The safety parameter of the potent compound (8b) was assessed using aspirin induced gastric ulceration animal model. [GRAPHIC].

Sodium as High-efficient Catalyst in Hydroboration of Unsaturated Compounds

The catalysts used to catalyze the hydroboration of nitriles or carbodiimides usually have some disadvantages such as complex structure, high cost, large pollution of environment and so on. It is an important development direction to use the main group metals instead of the transition metals to reduce the costs and realize green catalysis. In this paper, using NaH or NaOH as a catalyst, an efficient reaction of nitrile or carbodiimide with pinacol borane (HBPin) has been achieved. It was found that 3.5 mol% of NaH participated in the hydroboration reaction in a simple and effective method under slight solvent-free circumstances. In addition, intermolecular chemoselectivity hydroboration of nitrile and substrates with different functional groups was also investigated by employing three different catalysts. This reaction uses the inorganic alkali with simple structure, commercially available and low cost to synthesize organoborane compounds, which provides ideas for industrial development.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 611-64-3, you can contact me at any time and look forward to more communication. HPLC of Formula: https://www.ambeed.com/products/611-64-3.html.
