Lewis Acid Mediated Addition of Indoles and Alcohols to Tetronic Acid and Tetramic Acids

The electrophilic substitution of indoles with tetronic acid and N-acetyltetramic acid mediated by BF3OEt2 was investigated. This strategy allowed for the preparation of nine indole-substituted furan-2-ones (indolyl–lactones) and 3-pyrrolin-2-ones (indolyl–lactams) and is more straightforward than previously reported synthetic methods. During the course of our investigation, we also discovered a facile synthesis of tetronates and a tetramate via a BF3-mediated addition of alcohols to tetronic acid and N-acetyltetramic acid, respectively.

Copper Catalyzed Oxidative Arylation of Tertiary Carbon Centers

We describe herein a Cu(OTf)(2) catalyzed oxidative arylation of a tertiary carbon-containing substrate including aryl malononitriles, 3-aryl benzofuran-2-ones, and 3-aryl oxindoles. In some cases, the nitrile groups of the aryl malononitriles undergo further reactions leading to lactones or imines. These reaction conditions are applicable for a range of arenes, including phenols, anilines, anisoles, and heteroarenes. Mechanistic studies support the formation of a cationic intermediate via a two-electron oxidation.

Magnetic cobalt ferrite nanoparticles functionalized with citric acid as a green nanocatalyst for one-pot three-component sonochemical synthesis of substituted 3-pyrrolin-2-ones

A clean, convenient and facile approach for one-pot ultrasonic assisted synthesis of substituted 3-pyrrolin-2-ones from diethyl acetylenedicarboxylate, aniline and aldehyde derivatives is described. The reactions were carried out in the presence of an efficient, green and reusable acidic nanocatalyst, magnetic cobalt ferrite nanoparticles functionalized with citric acid (CoFe2O4@CA), with high yields under mild conditions. Also, use of ultrasound irradiation made this approach an attractive protocol for the synthesis of these products. The method has been successful in achieving the green chemistry objective. An energy efficient protocol using ultrasound irradiation instead of conventional heating or stirring and use of ethanol as a non-hazardous, inexpensive and green solvent in the one-step reaction against sequential reaction steps thus combining the features of both economic and environmental advantages.

Computational exploration of the 1,3-dipolar cycloaddition reaction of 7-isopropylidenebenzonorbornadiene with nitrile oxide and cyclic nitrone derivatives

The synthesis of isoxazolidine and isoxazole derivatives, versatile building blocks for the construction of a wide range of complex heterocyclic architectures in synthetic organic and medicinal chemistry, is efficiently achieved via the 1,3-dipolar cycloaddition reaction (1,3-DC). Herein, we report an extensive theoretical study on the peri-, regio-, stereo, and enantio-selectivities of 1,3-DC of 7-isopropylidenebenzonorbornadiene with nitrile oxide and cyclic nitrone derivatives using density functional theory calculations. Acetophenone-substituted nitrile oxide periselectively adds across the endocyclic olefinic bond of the dipolarophile to furnish the exo-cycloadduct as the major product, a reaction that has a rate constant of 1.88 x 10(9) s(-1). The endo approach of this periselective path is the closest competing pathway with a rate constant of 4.59 x 10(7) s(-1). Different substituents on the nitrile oxide do not affect the peri- and stereo-selectivity of the reaction. Diethyl ether solvation has no substantial effect on the energetic patterns observed in the gas phase computation. Also, we report a novel 1,3-DC between cyclic nitrone derivatives and 7-isopropylidenebenzonorbornadiene as an efficient way to generate isoxazolidine derivatives. Even though the reactions of the cyclic nitrone derivatives have slightly higher activation barriers than the acyclic nitrile oxide derivatives, the former is more enantioselective than the latter. Whereas electron-donating groups (EDGs) on the cyclic nitrone favor the formation of the exo-cycloadduct, electron-withdrawing groups (EWGs) favor the formation of the endo-cycloadduct. Both 1,3-dipoles add across the dipolarophile via a concerted asynchronous mechanism.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 272786-64-8. SDS of cas: 272786-64-8.

Effects of precipitated size of water-soluble amide-containing polymers and pore size of filters on recovery of Pd nanoparticles dispersed in acetone solution including colloidal polymer

When immobilized Pd nanoparticles (Pd NP) are used for the hydrogenation of nitrile butadiene rubber (NBR), some Pd NP leaks into the reaction medium. This Pd NP is expensive and must be recovered. In this study, Pd NP were recovered from an NBR acetone medium by precipitation with poly N-[2-(dimethylamino)ethyl] methacrylamide (poly(DAEMA)) and filtration. When poly(DAEMA) solution was added to the Pd NP NBR acetone solution, poly(DAEMA) interacted with Pd NP and formed a precipitate by dehydration. The poly(DAEMA) precipitate including trapped Pd NP was completely recovered by filtration through a filter with a pore size of 1 mu m. Poly(acrylamide) solutions of different molecular weights were tested for Pd NP recovery, and those with high molecular weights formed large quantities of precipitates, resulting in low recovery percentages. The concentration and molecular weight of the polymer used for the recovery of Pd NP by nanoprecipitation and filtration must be chosen carefully for optimal recovery. Especially, 40 kDa of PAA and 1 mu m filter pores were suitable for efficient Pd NP recovery.

Characterization of the amino acid adducts of the enedial derivative of teucrin A

The toxicity of germander, a herb used to treat obesity, is attributed to cytochrome P450 activation of the furan ring of its major diterpenoid component (teucrin A) into a reactive metabolite capable of adducting proteins. 1,4-Enedials have been proposed to be the reactive products of metabolism, possibly arising from a rearrangement of putative epoxide intermediates. We synthesized the enedial derivative of teucrin A as well as the enedial derived from a model furan, 3-(4-methoxy-benzyloxymethyl)-furan, by dimethyldioxirane oxidation and characterized the products of their reactions with amino acids and peptides. The reactions of the model enedial, 2-(4-methoxy-benzyloxymethyl)-but-2-enedial,withN-acetyl lysine (NAL) afforded regioisomeric N-alkyl-3-pyrrolin-2-ones, differing in the substitution on the double bond of the heterocyclic ring. Novel products formed in the reactions of the model enedial with N-acetyl cysteine (NAC) and both NAC/NAL uncovered the existence of tautomerization between the enedial and a hydroxyenal, which was manifest by the loss of 4-methoxybenzylalcohol and the incorporation of a second molecule of NAC. The reactions of teucrin A-enedial with NAC and NAL afforded analogues of the products observed with the model enedial, and the existence of the tautomeric equilibrium resulted in epimerization of the proton (H12) adjacent to the former furan ring. This work further illuminates the complex chemical behavior of unsaturated dialdehydes as an important class of toxic metabolites and lays the foundation for studies of the protein targets of teucrin A-enedial.

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 272786-64-8, in my other articles.
