Palladium(II)‐catalyzed intramolecular C─H alkenylation of cinnamides allows the atroposelective synthesis of axially chiral 4‐arylquinolones, with the chirality being installed by ring formation. DFT studies have shown that the reaction proceeds by prior activation of the alkene and the enantioselectivity is determined during the β‐hydride elimination

6-Nitroquinoline undergoes direct cyclocondensation with aromatic hydrazones in the presence of sodium hydride in DMF at −10 °C, giving the corresponding 3-aryl-1(3)H-pyrazolo[3,4-f]quinolines and/or 3-aryl[1.2.4]triazino[6,5-f]quinolines in low to ...

QUINOLINE DERIVATIVES. PART IV.
In view of the fact that glyoxatinoquinolines of Narang and Räy have the requisite antiseptic properties against paramaecia, benziminazolyIquinoline derivatives, which are expected to possess antimalarial properties, have been ...

Mo‐Catalyzed Synthesis of 3‐Substituted Quinolines From Nitroarenes and Aldehydes
A one‐pot Friedländer synthesis of 3‐substituted quinolines from readily available o‐nitrobenzaldehydes and aldehydes or acetals has been developed under dioxomolybdenum(VI) catalysis. Pinacol acts as a benign reductant, enabling in situ nitroarene reduction and annulation without isolation of o‐aminobenzaldehydes and provides access to diverse ...

The research progress in polyethylene oxide polymer electrolytes
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...

Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.
