Nano-ferrite-supported Cu nanoparticles (Fe-dopamine-Cu NPs) catalyzed anti-Markovnikov-selective hydroboration of alkenes with B(2)pin(2) is reported under mild reaction conditions. This protocol can be applied to a broad range of substrates with high functional group compatibility. In addition, we demonstrated the use of Fe-dopamine-Cu NPs as a catalyst for the beta-borylation of alpha,beta-unsaturated ketones and ester, providing alkylboronate esters in up to 98% yield. Reuse of the magnetically recyclable catalyst resulted in no significant loss of activity in up to five reaction runs for both systems.

The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

Herein, we report a radical borylation of aromatic amines through a homolytic C(sp(2))-N bond cleavage. This method capitalizes on a simple and mild activation via a pyrylium reagent ((Sc)Pyry-OTf) thus priming the amino group for reactivity. The combination of terpyridine and a diboron reagent triggers a radical reaction which cleaves the C(sp(2))-N bond and forges a new C(sp(2))-B bond. The unique non-planar structure of the pyridinium intermediate, provides the necessary driving force for the aryl radical formation. The method permits borylation of a wide variety of aromatic amines indistinctively of the electronic environment.

Methylthiolation reactions are usually explored to access organosulfur compounds using methanethiol, an extremely flammable and toxic compound. Herein, methylthiomethyl esters were successfully applied as novel methylthiolation reagents in a low cost, transition-metal-free methodology. These reagents allowed the methylthiolation of a wide scope of chalcones, acyl ester derivatives and Morita-Baylis-Hillman acetates with good group tolerance, affording the methylthiolated products in moderate to excellent yields. The reaction mechanism was investigated through several control experiments, as well as by theoretical calculations employing Density Functional Theory. The results strongly support that a sulfurane and a sulfonium ylide appear as key intermediates and that a Pummerer type rearrangement is also crucial for the formation of this novel reagent. Furthermore, the methylthiolation mechanism is likely to proceed through the nucleophilic attack of the reagent, followed by an entropically favoured step involving the acetate attack to the positively charged species, then releasing the product.

A dehydrative C- and S-alkylation procedure by nucleophilic substitution of gamma-hydroxysufones with arenes and thiophenols is reported. This study represents an elegant and ecological concept to construct C-C and C-S bonds leading to unsymmetrical 1,1- and 3,3-branched propanes. The gamma-hydroxysufones underwent BF3 center dot OEt2-mediated dehydrative arylation and thiolation at room temperature and elimination at 40 degrees C. The nucleophile attack occurred on the less hindered side of a planar benzylic carbocation to furnish the title compounds with good diastereoselectivity.

A series of 1,3,5-triazine analogues, incorporating aminobenzene sulfonamide, aminoalcohol/ phenol, piperazine, chalcone, or stilbene structural motifs, were evaluated as potential antioxidants. The compounds were prepared by using step-by-step nucleophilic substitution of chlorine atoms in starting 2,4,6-trichloro-1,3,5-triazine. Reactions were catalyzed by Cu(I)-supported on a weakly acidic resin. The radical scavenging activity was determined in terms of %inhibition activity and EC50, using the ABTS method. Trolox and ascorbic acid (ASA) were used as standards. In the lowest concentration 1 X 10(-4) M, the %inhibition activity values at 0 min were comparable with both standards at least for 10 compounds. After 60 min, compounds 5, 6, 13, and 25 showed nearly twice %inhibition (73.44-87.09%) in comparison with the standards (Trolox = 41.49%; ASA = 31.07%). Values of EC50 at 60 min (17.16-27.78 mu M) were 5 times lower for compounds 5, 6, 13, and 25 than EC50 of both standards (trolox = 178.33 mu M; ASA = 147.47 mu M). Values of EC50 correlated with %inhibition activity. Based on these results, the presented 1,3,5-triazine analogues have a high potential in the treatment of illnesses caused or related to oxidative stress.

The transfer hydrogenation of ketones catalyzed by transition metal complexes has attracted much attention. A series of ruthenium(11) complexes bearing 2,6-bis(5,6-dialkyl-1,2,4-triazin-3-yl)pyridine ligands (R-BTPs) were synthesized and characterized by NMR analysis and X-ray diffraction. These ruthenium (II) complexes were applied in the transfer hydrogenation of ketones. Their different catalytic activity were attributed to the alkyl arms on the 2,6-bis(5,6-dialkyl-1,2,4-triazin-3-yl)pyridine. As the length of the alkyl arms rising, the catalytic activities of the complex catalysts decreased. By means of 0.4 mol % catalyst RuCl2(PPh3)(3-methylbutyl-BTP) in refluxing 2-propanol, a variety of ketones were reduced to their corresponding alcohols with >95% conversion over a period of 3 h.

An olefinic difunctionalization method of enones was presented hereviaaerobic visible-light catalysis. A novel reactivity was showcased in conjunction with the selective Csp(2)-C(CO) bond activation of enones, which provided a convenient method for the preparation of various beta-thiolated-alpha-functionalized compounds. Moreover, the preliminary investigation of the mechanism indicated that a beta-peroxysulfide intermediate was formed under the promotion of visible light under an oxygen atmosphere, which finally induced the unexpected C-C bond cleavage.

An article Orange peel volatile oil: A green solvent for propolis extraction, enhanced alpha-amylase inhibition activity WOS:000527228700001 published article about ANTIOXIDANT ACTIVITY; PHENOLIC COMPOSITION; TURKISH PROPOLIS in [Keskin, Saban] Bilecik Seyh Edebali Univ, Vocat Sch Hlth Serv, Bilecik, Turkey in 2020, Cited 24.

Orange peel oil contains high amount of d-limonene which is reported to have antidiabetic activity. Propolis contains many biologically active compounds like phenolic acids, flavonoids and terpenes. Because of its rich phenolic composition, antidiabetic activity of propolis has also been shown in literature. Consumption of raw propolis is limited because of its resinous nature. It should be extracted to convert it into consumable form. Ethanol is the most used solvent for this purpose. Ethanol is the limiting factor for propolis consumption either for religious concerns or being harmful for human health. There is an increasing need for new, compatible and healthier solvents for propolis extraction. This is the first paper describing the extraction of propolis with orange peel oil. 1:10 (g/v) ratio was used for extraction. Orange peel oil (OPO), orange peel oil propolis extract (OPOPE) and ethanol propolis extract (EPE) were separately analysed by using GC-MS technique. Total phenolic content of oil and propolis extract was also carried out. Inhibition of alpha-amylase from barley malt with new extract was also reported. It was found that OPOPE was rich in volatile compounds of propolis, phenolic acid derivatives and free fatty acids. It was observed that OPOPE showed higher inhibition on alpha-amylase enzyme (IC50 0.196 mg/mL). It can be concluded that orange peel oil could be used as solvent for preparing propolis extract. Propolis extract obtained with orange peel oil could also be used as complementary medicine for the treatment of type 2 diabetes.
