An I2-mediated metal-free oxidative C-N bond formation methodology has been established for the regioselective pyrazole synthesis. This practical and eco-friendly one-pot protocol requires no isolation of less stable intermediates hydrazones provides a facile access to variety di-, tri-, tetrasubstituted (aryl, alkyl, and/or vinyl) pyrazoles from readily available α,β-unsaturated aldehydes/ketones hydrazine salts.
2-Amino-substituted 1,3,4-oxadiazoles and 1,3,4-thiadiazoles were synthesized via condensation of semicarbazide/thiosemicarbazide the corresponding aldehydes followed by I2-mediated oxidative C–O/C–S bond formation. This transition-metal-free sequential synthesis process is compatible with aromatic, aliphatic, cinnamic aldehydes, providing facile access to a variety diazole derivatives bearing 2-amino substituent in an efficient scalable fashion.
Abstract The development of robust electrocatalysts for electrocatalytic hydrogenation (ECH) guaiacol and related lignin model monomers is necessary the stabilization or upgrading bio‐oil. Additionally, efficiency biomass conversion to bio‐oil products remains below minimum requirements its implementation at scale. Herein, a PtNiB/CMK‐3 catalyst with pronounced ECH performance in under optimally mild conditions, through modulation strategy that modified electronic structure PtNi via boron...
The one‐electron reduction (OER) can profoundly affect the structure and reactivity of organic compounds. OER induced radical decarboxylative functionalizations redox‐active esters have gained wide concerns in this century. In review, we present recent advances using as carbon‐centered precursors to form carbon–carbon carbon–heteroatom bonds.
In this study, thermoresponsive and mussel-inspired polypeptides were synthesized using ring-opening polymerization of α-amino acid derivatives N-carboxyanhydride (NCA). The tissue adhesive properties these evaluated in vitro strength tests on porcine skin bone. results indicated that the species functional polypeptide side groups temperature have a significant influence adhesion strength. maximum lap-shear was 101.2 kPa, tensile bone 603 kPa. vivo antibleeding activity ability also rat...
The newly discovered Tianzhu transtensional fault system cuts across the WNW-trending Qilian Shan orogen and thrust strike-slip systems on northeastern margin of Tibetan Plateau. Using high-resolution satellite images, geomorphic mapping, trenching, radiocarbon optically stimulated luminescence dating, we found that consists Western Basin, Jinqianghe, Xuanmahe, Eastern Gulang, Haxi faults, exhibiting active oblique normal faulting during late Quaternary. experiences at least left-lateral...
The double-oxidative dehydrogenative (DOD) cyclization represents one of the most straightforward and atom-economical methods for cyclic structure formation. A Cu(II)/DDQ/O2 system-catalyzed DOD [4 + 2]-annulation/oxidative aromatization tandem reaction readily available glycine derivatives alkylbenzenes was established. This approach facilitates rapid access to a broad scope substituted quinoline-2-carboxylate derivatives, an important motif in drug discovery. could feasibly be applied 10...
PLGA nanoparticles with bicyclol and Br-NBP were for the first time successfully characterized by a laser trapping/confocal Raman spectroscopic technique only using individual nanoparticles.
A novel electrochemical system for sulfenylation of indoles with disulfides to generate 3-sulfenylindoles via C-S bond formation mediated by potassium iodide at a low potential was developed. Iodine electrogenerated from ions graphite anode and showed high catalytic activity the reactions. variety aromatic, heteroaromatic aliphatic could react 2-methlyindole synthesize corresponding in good excellent yields. In addition, protected unprotected various groups, especially electron-donating also...
