The present disclosure describes biaryl triazole compounds, as well as their compositions and methods of use. The compounds inhibit the activity of macrophage migration inhibitory factor and are useful for the treatment of diseases, e.g., inflammatory diseases and cancer.
An efficient palladium-catalyzed dearomatizing [2+2+1] carbocyclization of 1,7-enynes with iodophenols has been developed. A type of tetracyclicscaffold was built in this reaction, exhibiting a broad substrate scope with moderate to excellent yields. More importantly, this method provides a potential strategy for the synthesis of tetracyclic skeleton natural products.
synthesis of fluorinated benzofurans from polyfluorophenols has been accomplished by means of a sigmatropic dearomatization/defluorination strategy composed of three processes: (1) interrupted Pummerer reaction of ketene dithioacetal monoxides with polyfluorophenols followed by [3,3] sigmatropicrearrangement, (2) Zn‐mediated smooth reductive removal of fluoride from the dearomatized intermediate, and

6-difluorophenols with aryl sulfoxides and nucleophiles has been accomplished. The reaction is composed of (1) Pummerer-based [3,3] sigmatropic dearomatization to generate 2,4-cyclohexadienone, (2) Michael addition of a nucleophile, and (3) liberation of HF for rearomatization. Besides the [3,3] rearrangement, [2,3] sigmatropic rearrangement from sulfonium ylide generated from alkyl sulfoxide promotes the dearomatization
Oxidativedimerization of terminal alkynes (Glaser coupling) triggered by spirofluorene derived macrocyclic phenanthroline–Cu complexes was implemented to synthesize a series of novel [2]rotaxanes. Size and structural variations among the components and their implications on the dynamic behaviour were investigated in detail through 1H and 19F NMR spectroscopy. Strong perturbations in the NMR spectra
由螺芴衍生的大环菲咯啉-铜配合物引发的末端炔烃的氧化二聚反应(格拉泽偶联)被用于合成一系列新型 [2] 轮烷。通过1 H 和19 F NMR 光谱详细研究了组分之间的尺寸和结构变化及其对动态行为的影响。具有低对称性的取代大环组分的轮烷的 NMR 光谱中的强烈扰动表明环组分沿轴组分的非对称分布。在一些 [2] 轮烷中,观察到环组分位于 1,3-二炔部分附近。
