Wilson, Katy B.; Nedzbala, Hannah S.; Simpson, Spenser R.; Ericson, Megan N.; Westendorff, Karl S.; Chordia, Mahendra D.; Dickie, Diane A.; Harman, W. Dean published the artcile< Hydroamination of Dihapto-Coordinated Benzene and Diene Complexes of Tungsten: Fundamental Studies and the Synthesis of γ-Lycorane>, Recommanded Product: 4-Bromobenzylamine, the main research area is hydroamination dihapto benzene diene tungsten complex; gamma lycorane preparation; crystal mol structure dihapto alkene tungsten complex; arenes; cyclohexenes; dearomatization; dienes; hydroamination; lycorane; nitrosyl ligands; tungsten.

Reactions are described for complexes of the form WTp(NO)(PMe3)(η2-arene) and various amines, where the arene is benzene or benzene with an electron-withdrawing substituent (CF3, SO2Ph, SO2Me). The arene complex is first protonated to form an η2-arenium species, which then selectively adds the amine. The resulting η2-5-amino-1,3-cyclohexadiene complexes can then be subjected to the same sequence with a second nucleophile to form 3-aminocyclohexene complexes, where up to three stereocenters originate from the arene carbons. Alternatively, 1,3-cyclohexadiene complexes containing an ester group at the 5 position (also prepared from an arene) can be treated with acid followed by an amine to form trisubstituted 3-aminocyclohexenes. When the amine is primary, ring closure can occur to form a cis-fused bicyclic γ-lactam. Highly functionalized cyclohexenes can be liberated from the tungsten through oxidative decomplexation. The potential utility of this methodol. is demonstrated in the synthesis of the alkaloid γ-lycorane. An enantioenriched synthesis of a lactam precursor to γ-lycorane is also described. This compound is prepared from an enantioenriched version of the tungsten benzene complex. Regio- and stereochem. assignments for the reported compounds are supported by detailed 2D-NMR anal. and 13 mol. structure determinations (SC-XRD).

Adhikary, Saswati; Majumder, Leena; Pakrashy, Sourav; Srinath, Ravuri; Mukherjee, Kaustuv; Mandal, Chitra; Banerji, Biswadip published the artcile< Polysubstituted Imidazoles as LysoTracker Molecules: Their Synthesis via Iodine/H2O and Cell-Imaging Studies>, Name: 4-Bromobenzylamine, the main research area is imidazole regioselective synthesis fluorescent lysosome staining probe.

An iodine-catalyzed, environmentally benign one-pot methodol. has been developed for the synthesis of diverse substituted imidazoles. This transition-metal-free, aerobic, water-mediated cyclization reaction is operationally simple and works well with different amines or aldehydes by multiple C-N bond formations with satisfactory yield. The methodol. is regioselective as well as scalable. These imidazole derivatives show excellent fluorescence properties both in the solid and solution phase, which is further extended to live-cell imaging. Due to the suitable fluorescence properties of these scaffolds, lysosome-directing groups are incorporated in two of these derivatized imidazoles to track intracellular lysosomes. Successfully, those mols. show bright blue fluorescence while detecting lysosomes in human or murine cells and can be considered to be rapid lysosome-staining probes.

Li, Peiyu; Dong, Xiaoyun; Zhang, Ya; Lang, Xianjun; Wang, Cheng published the artcile< An azine-linked 2D porphyrinic covalent organic framework for red light photocatalytic oxidative coupling of amines>, Related Products of 3959-07-7, the main research area is azine porphyrinic covalent organic framework benzylamine photocatalytic oxidative coupling.

The construction of two-dimensional covalent organic frameworks (2D COFs) with robust stability for photocatalysis has gained intensive attention recently. Herein, we report the design and synthesis of a highly crystalline azine-linked porphyrinic 2D COF (Por-HZ-COF). Our results clearly show that Por-HZ-COF adopts an eclipsed AA stacking structure with a high Brunauer-Emmett-Teller (BET) sp. surface area of 1586 m2/g. In addition, Por-HZ-COF is chem. stable under various conditions, even in 12 M sodium hydroxide aqueous solution or 9 M hydrochloric acid. Moreover, Por-HZ-COF can be used for the photocatalytic aerobic oxidative coupling of benzylamines under red light irradiation with high activity and good reusability. This study demonstrates a novel robust 2D COF with azine linkage that has promising applications in photocatalysis.

Yang, Xue; Huang, Tao; Gao, Shuiying; Cao, Rong published the artcile< Boosting photocatalytic oxidative coupling of amines by a Ru-complex-sensitized metal-organic framework>, Category: bromides-buliding-blocks, the main research area is oxidative coupling photocatalyst metal organic framework.

Visible-light-driven selective photocatalytic organic synthesis has recently become a topic of great interest due to its environmental friendliness and sustainability. It is demanding for photocatalysis to utilize the wider range of light, such as visible light, and its performance is often plagued by the sluggish separation of photogenerated charge carriers. An approach is now reported to address these issues by incorporating light harvesting RuII-polypyridyl complexes into a semiconductor-type metal-organic framework (MIL-125). Delightedly, the obtained Ru(bpy)3@MIL-125 photocatalyst presents a remarkably stable and high photoactivity toward the selective oxidative coupling of amines under ambient air with visible light irradiation (λ > 440 nm). The mechanistic investigation unveiled that both effectively photoexcited electrons transfer from [Ru(bpy)3]Cl2 to MIL-125 and the interaction of C-H bonds with superoxide radical (O·-2) play a critical role in photo-catalyzing selective aerobic oxidative coupling of amines. This work highlights a significant role of MOFs as heterogeneous photocatalysts in photocatalytic organic transformations.

Via an imine-protection strategy, the authors herein present an unprecedented copper-catalyzed oxidative multicomponent annulation reaction for direct synthesis of quinazolinones. The construction of various products is achieved via formation of three C-N and one C-C bonds in conjunction with the benzylic functionalization. The merits of easily available feedstocks, naturally abundant catalyst, good functional group and substrate compatibility, and release of H2O as the byproduct make the developed chem. a practical way to access quinazolinones.

Xie, Chao; Song, Jinliang; Hua, Manli; Hu, Yue; Huang, Xin; Wu, Haoran; Yang, Guanying; Han, Buxing published the artcile< Ambient-Temperature Synthesis of Primary Amines via Reductive Amination of Carbonyl Compounds>, Recommanded Product: 4-Bromobenzylamine, the main research area is primary amine preparation reductive amination titanium phosphate Ruthenium nanocatalyst.

Efficient synthesis of primary amines via low-temperature reductive amination of carbonyl compounds using NH3 and H2 as the nitrogen and hydrogen resources is highly desired and challenging in the chem. community. Herein, we employed naturally occurring phytic acid as a renewable precursor to fabricate titanium phosphate (TiP)-supported Ru nanocatalysts with different reduction degrees of RuO2 (Ru/TiP-x, x represents the reduction temperature) by combining ball milling and molten-salt processes. Very interestingly, the obtained Ru/TiP-100 had good catalytic performance for the reductive amination of carbonyl compounds at ambient temperature, resulting from the synergistic cooperation of the support (TiP) and the Ru/RuO2 with a suitable proportion of Ru0 (52%). Various carbonyl compounds could be efficiently converted into the corresponding primary amines with high yields. More importantly, the conversion of other substrates with reducible groups could also be achieved at ambient temperature Detailed investigations indicated that the partially reduced Ru and the support (TiP) were indispensable. The high activity and selectivity of Ru/TiP-100 catalyst originates from the relatively high acidity and the suitable electron d. of metallic Ru0.
