Major anti-inflammatoryagents, steroids and cyclooxygenase, were proved to have serious side effects. Here, a series of chalconederivatives were synthesized and screened for anti-inflammatory activities. QSAR study revealed that the presence of electron-withdrawing groups in B-ring and electron-donating groups in A-ring of chalcones was important for inhibition of LPS-induced IL-6 expression. Further
A visible-light-driven and room temperature photo-Wolff-Kischner reaction of sulfur ylides and N-tosylhydrazones has been developed for the first time to provide modular access to alkene synthesis. The high functional group tolerance and broad substrate scope were demonstrated by more than 60 examples. Both E- and Z-olefinic stereochemistry in the products could be controlled with excellent stereoselectivity
One-Pot Synthesis of 4-Substituted 1<i>H</i>-[1,2,3]triazolo[4,5-<i>c</i>]quinolines Through CuO-Promoted Tandem Cyclization Reactions of (<i>E</i>)-3-(2-Bromoaryl)-1-arylprop-2-en-1-ones with Sodium Azide
A facile and efficient protocol for the synthesis of 4-substituted-1H-[1,2,3]triazolo[4,5-c]quinolinesthrough a CuO-promotedtandemcyclizationreaction has been developed. This method allows for the construction of two heterocyclic rings in a one-potreaction of readily available (E)-3-(2-bromoaryl)-1-arylprop-2-en-1-ones and sodiumazide without the addition of any additive. A series of triazole-fused
