Ung, Sosthene P.-M.; Perepichka, Inna; Li, Chao-Jun published the artcile< Visible-Light Mediated Photooxidative Phosphorylation of Benzylamines: A Novel and Mild Pathway Towards α-Aminophosphorus Compounds>, COA of Formula: C7H8BrN, the main research area is benzylamine oxidative photochem phosphinylation preparation aminophosphine oxide; benzylidene benzylamine photochem generation addition preparation secondary aminophosphine oxide; iridium phenylpyridine bipyridine photocatalyst benzylamine oxidative preparation aminophosphine oxide.

Traditional syntheses of α-aminophosphorus therapeutic targets proceed through the hydrophosphorylation of C:N or C:O bonds, thus necessitating preliminary oxidized substrates. Cross-dehydrogenative coupling strategies can bypass this extra oxidation step by oxidizing simpler substrates in situ before phosphorylating them, but those protocols can suffer from the use of toxic stoichiometric oxidants. Photochem. strategies can access those oxidized intermediates without any harsh conditions and can use mol. oxygen as a benign and sustainable oxidant. We report herein a simple protocol using visible light, phosphinylidenes and benzylamine derivatives for the synthesis of α-aminophosphorus products under aerobic conditions and using an iridium photosensitizer.

Zheng, Bingxiao; Xu, Jiao; Song, Jinliang; Wu, Haihong; Mei, Xuelei; Zhang, Kaili; Han, Wanying; Wu, Wei; He, Mingyuan; Han, Buxing published the artcile< Nanoparticles and single atoms of cobalt synergistically enabled low-temperature reductive amination of carbonyl compounds>, Category: bromides-buliding-blocks, the main research area is primary amine preparation; aldehyde ketone reductive amination cobalt catalyst.

Herein, authors designed several Co-based catalysts (denoted as Co@C-N(x), where x represents the pyrolysis temperature) by the pyrolysis of the metal-organic framework ZIF-67 at different temperatures Very interestingly, the prepared Co@C-N(800) could efficiently catalyze the reductive amination of various aldehydes/ketones to synthesize the corresponding primary amines with high yields at 35°C. Besides non-noble metal and mild temperature, the other unique advantage of the catalyst was that the substrates with different reduction-sensitive groups could be converted into primary amines selectively because the Co-based catalyst was not active for these groups at low temperature Systematic anal. revealed that the catalyst was composed of graphene encapsulated Co nanoparticles and atomically dispersed Co-Nx sites. The Co particles promoted the hydrogenation step, while the Co-Nx sites acted as acidic sites to activate the intermediate (Schiff base). The synergistic effect of metallic Co particles and Co-Nx sites is crucial for the excellent performance of the catalyst Co@C-N(800). To the best of knowledge, this is the first study on efficient synthesis of primary amines via reductive amination of carbonyl compounds over earth-abundant metal-based catalysts at low temperature (35°C).

Perez-Castillo, Yunierkis; Montes, Ricardo Carneiro; da Silva, Cecilia Rocha; Neto, Joao Batista de Andrade; Dias, Celidarque da Silva; Brunna Sucupira Duarte, Allana; Junior, Helio Vitoriano Nobre; de Sousa, Damiao Pergentino published the artcile< Antifungal Activity of N-(4-Halobenzyl)amides against Candida spp. and Molecular Modeling Studies>, SDS of cas: 3959-07-7, the main research area is Candida halobenzyl amide mol modeling antifungal activity; Candida auris; anticandidal drugs; antimicrobial activity; benzoic acid; candidiasis; cinnamic acid; fungi; molecular docking; natural products; plants.

Fungal infections remain a high-incidence worldwide health problem that is aggravated by limited therapeutic options and the emergence of drug-resistant strains. Cinnamic and benzoic acid amides have previously shown bioactivity against different species belonging to the Candida genus. Here, 20 cinnamic and benzoic acid amides were synthesized and tested for inhibition of C. krusei ATCC 14243 and C. parapsilosis ATCC 22019. Five compounds inhibited the Candida strains tested, with compound 16 (MIC = 7.8 μg/mL) producing stronger antifungal activity than fluconazole (MIC = 16 μg/mL) against C. krusei ATCC 14243. It was also tested against eight Candida strains, including five clin. strains resistant to fluconazole, and showed an inhibitory effect against all strains tested (MIC = 85.3-341.3 μg/mL). The MIC value against C. krusei ATCC 6258 was 85.3 mcg/mL, while against C. krusei ATCC 14243, it was 10.9 times smaller. This strain had greater sensitivity to the antifungal action of compound 16. The inhibition of C. krusei ATCC 14243 and C. parapsilosis ATCC 22019 was also achieved by compounds 2, 9, 12, 14 and 15. Computational experiments combining target fishing, mol. docking and mol. dynamics simulations were performed to study the potential mechanism of action of compound 16 against C. krusei. From these, a multi-target mechanism of action is proposed for this compound that involves proteins related to critical cellular processes such as the redox balance, kinases-mediated signaling, protein folding and cell wall synthesis. The modeling results might guide future experiments focusing on the wet-lab investigation of the mechanism of action of this series of compounds, as well as on the optimization of their inhibitory potency.

Takeda, Mitsumi; Maejima, Saki; Yamaguchi, Eiji; Itoh, Akichika published the artcile< Iodine-mediated direct α-amination of dimethyl methylmalonate using non-protected amines>, SDS of cas: 3959-07-7, the main research area is dimethyl methylmalonate amine iodine regioselective amination; alkylamino dimethyl methylmalonate preparation.

In this study, direct C-N bond formation was achieved via the reaction of a di-Me methylmalonate with various amines in the presence of mol. iodine to produce α-aminocarbonyl compounds This versatile methodol. of the α-amination of a carbonyl-containing compound involves the in situ iodination of the di-Me methylmalonate, thus promoting the formation of its enolate isomer, which then facilitates its nucleophilic substitution reaction with an amine. This strategy is highly practical and can be used in industry due to its requirement of only readily available reagents without any pre-preparation of the amines and other substrates.

Sheng, Wenlong; Shi, Ji-Long; Hao, Huimin; Li, Xia; Lang, Xianjun published the artcile< Polyimide-TiO2 hybrid photocatalysis: Visible light-promoted selective aerobic oxidation of amines>, Computed Properties of 3959-07-7, the main research area is visible light promoted selective aerobic oxidation amine; Polyimide titania hybrid photocatalysis.

Polyimides are a class of high-performance polymers with good thermal and chem. stability. One specific polyimide can be formed via thermal polymerization of melamine (MA) and pyromellitic dianhydride (PMDA) precursors. Herein, polyimide-TiO2 hybrids were straightforwardly synthesized with a mixture of MA, PMDA and TiO2 by annealing at 325 °C. The crystal phase of anatase TiO2 can be preserved and polyimide can be formed on the surface of TiO2 to enable visible light absorption and high sp. surface areas for the polyimide-TiO2 hybrid. Next, this polyimide-TiO2 hybrid as a photocatalyst were successfully applied for visible light-promoted selective aerobic oxidation of amines into imines under irradiation of 460 nm blue light-emitting diodes (LEDs). With 4 mol% of (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) as the co-catalyst, polyimide-TiO2 hybrid photocatalyst reached 8 times of that of pristine TiO2 for the selective aerobic oxidation of benzylamine. Overall, the cooperative photocatalysis of polyimide-TiO2 hybrid and TEMPO was demonstrably efficient for visible light-promoted selective oxidation of amines with aerial O2 as the oxidant. Moreover, by means of reactive oxygen species (ROS) quenching experiments and in-situ ESR spectroscopy, superoxide anion radical (O·-2) was certified as the crucial ROS in coupling polyimide-TiO2 hybrid photocatalysis and TEMPO catalysis. This work suggests that hybridization of metal oxide semiconductor with polymer like polyimides is viable to forge visible light photocatalysts.

A tandem aerobic oxidation protocol has been developed for the facile synthesis of indole-3-carboxylates. Two readily available starting materials, anilines and benzylamines, were efficiently cross-coupled under the o-naphthoquinone-catalyzed aerobic oxidation conditions to the corresponding 2-arylmethyleneaminophenylacetates that in turn smoothly underwent the Cu(II)-catalyzed intramol. Mannich reaction. The resulting indoline derivatives were aerobically oxidized to indole-3-carboxylates, providing a ready access to indole derivatives from two simple amine derivatives

Three hydrophilic two-dimensional (2D) COFs achieved by a polycondensation reaction of 2,5-dimethoxyterephthalohydrazide (DMTH), 1,3,5-triformylbenzene (TFB) and 2-hydroxy-1,3,5-benzene tricarbaldehyde (SOH) under solvothermal conditions was reported. The resulted COF materials, TFB-XX-DMTH (XX = 33, 50 and 66, corresponding to a molar ratio of TFB/SOH = 1 : 2, 1 : 1 and 2 : 1), were successfully constructed by a three-component in-situ assembly strategy and thus exhibited high crystallinity, large surface areas (up to 1808 m2 g-1) and good thermal and chem. stability. Moreover, benefiting from the enhanced charge separation efficiency and high hydrophilicity, the TFB-XX-DMTH materials were employed as photocatalysts for visible-light-driven oxidative coupling reactions of benzylamines in aqueous solution The photocatalytic performance with high conversion, selectivity and recyclability could be attributed to a combined result of efficient generation, migration and separation of photogenerated carriers in such a platform. This results provide insights into the structure-function correlation of COF photocatalysts and also highlight their potential in developing photofunctional COFs for sustainable organic transformations.

Zhang, Shishen; Chen, Kelong; Peng, Wen; Huang, Jianhua published the artcile< g-C3N4/Uio-66-NH2 nanocomposites with enhanced visible light photocatalytic activity for hydrogen evolution and oxidation of amines to imines>, Synthetic Route of 3959-07-7, the main research area is water splitting photocatalysis photooxidation amine imine nanocomposite MOF.

G-C3N4/Uio-66-NH2 (CNUIO) nanocomposites were prepared by growing an NH2-mediated zirconium-based metal-organic framework (Uio-66-NH2) in the presence of g-C3N4 nanotubes. CNUIO exhibited efficient photocatalytic performance in the oxidation of amines to imines and hydrogen production under visible light illumination. The optimal Uio-66-NH2 content in CNUIO was 16.7 wt% with a H2-generation rate of 152.2μmol h-1, which is about 1.7 and 39 times as high as those of g-C3N4 and Uio-66-NH2, resp. The optimal conversion rate of benzylamine was 58.9%, which is about 3.4 and 10.5 times as high as those of g-C3N4 and Uio-66-NH2, resp. The probable photocatalytic mechanism of the CNUIO composite was investigated. This work provides a new insight into the fact that g-C3N4/MOF photocatalysts have great potential application in hydrogen production and organic synthesis.
