Abstract The first example of cobalt‐catalyzed C( sp 2 )−H carbonylation benzylamines using a traceless directing group is reported, which was successfully applied to the synthesis N −unprotected iso‐indolinones through direct C−H/N−H bonds activation. This protocol tolerates variety functional groups and provides facile efficient method for formal (+)‐garenoxacin. magnified image
A series of air-stable, easily accessible tridentate ferrocene-based diamine-phosphine sulfonamide (f-diaphos) ligands were successfully developed for iridium-catalyzed asymmetric hydrogenation ketones. The f-diaphos exhibited excellent enantioselectivity and superb reactivity in Ir-catalyzed ketones (for arylalkyl ketones, (S)-selectivity, up to 99.4% ee, 100 000 TON; diaryl (R)-selectivity, 98.2% 10 TON). This protocol could be conducted on gram scale, thereby providing a chance various drugs.
A traceless directing group assisted Co-catalyzed C(sp2)-H carbonylation of ortho-arylanilines for the synthesis free ( NH)-phenanthridinones in metal-based-oxidant-free fashion was accomplished. This protocol employs diisopropyl azodicarboxylate as CO source and oxygen sole oxidant, provides good yields with various functional tolerance. The methodology has been applied total PARP inhibitor PJ-34. Furthermore, kinetic isotopic effect experiments reveal C-H bond cleavage probably occurred...
In this article, biodiesel was prepared using a novel free liquid lipase A from Candida antarctica (CALA) as catalyst in the presence of excess water. The methanol tolerance CALA investigated. effect reaction conditions, including molar ratio soybean oil to methanol, water load, temperature, and time, evaluated. Reaction thermodynamics kinetics were also analyzed. Results showed that excellent system one-step addition can be used prepare with load 12–14%. influence three transesterification...
The first example of the metal- and solvent-free B(C6F5)3-catalyzed Markovnikov addition indoles to aryl alkynes was disclosed. Both N-H N-protected were tolerated, leading a wide spectrum versatile bis(indolyl)alkanes in moderate good yields with high regioselectivities.
Abstract The first example of a Cu‐catalyzed and 4‐OH‐TEMPO mediated intermolecular [3+3] annulation saturated ketones with β ‐enamino esters is reported herein, which was successfully used for the synthesis versatile nicotinates through sequential β‐ C( sp 3 )‐H bond alkenylation, enamine‐carbonyl condensation aromatization. This protocol tolerates variety functional groups, thereby providing practical efficient method fabrication 5H ‐chromeno[4,3‐b]pyridin‐5‐one skeletons. magnified image
Visible light has been widely studied for possible applications in food industry as being a kind of clean energy. Presently, the influences illumination pretreatment on soybean oil quality followed by conventional activated clay bleaching, including color, fatty acid composition, oxidation stability, and micronutrient content, were investigated. Results demonstrated that increased color differences between non-illuminated illuminated oils, which indicated exposure could improve decoloring...
A modification of granular activated carbon (GAC) by Fe–Mn–O was proposed to improve the catalytic activity GAC for enhanced mineralization aqueous RB5. The efficiency, kinetics, and possible mechanism ozonation RB5 catalyzed mGAC have been investigated. exerted in a slight promotion decoloration. An additional 18% TOC removal efficiency observed degradation O3/mGAC compared with O3/GAC under identical experimental conditions within 1 h. pH an evident impact on RB5, maximal achieved at 7....
In this paper, a mechanical lock is first proposed and designed for LED silicone lens mounting. Since has many new applications in areas such as automobile headlight, micro-projector local network optical communication, potential serious issue must be solved. Due to the poor adhension between mostly materials including silicon, may drop off from silicon substrate during usage, especially when used those harsh environments with thermal shock, headlight application which also needed...
The quality of cooking oils is a prominent factor that affects the compositions fumes during heat cooking. Presently, hazardous compounds, including aldehydes, ketones, polycyclic aromatic hydrocarbons (PAHs), and particulate matter (PM) in emitted from heated soybean with different refining levels were characterized, their health risks assessed. Results demonstrated neutralized oil showed highest emission aldehydes ketones (796.52 ± 29.67 μg/m3), whereas refined lowest (328.06 24.64 μg/m3)....
