vinyl arenes with trimethylsilylazide and molecular oxygen as stoichiometric oxidant was achieved. In contrast to photocatalysts based on iridium, ruthenium, or organic dyes, [Cu(dap)2]Cl or [Cu(dap)Cl2] were found to be unique for this transformation, which is attributed to their ability to interact with the substrates through ligand exchange and rebound mechanisms. CuII is proposed as the catalytically
用三甲基甲硅烷基叠氮化物和分子氧作为化学计量氧化剂实现了乙烯基芳烃的可见光加速氧化叠氮化。与基于铱,钌或有机染料的光催化剂相反,发现[Cu(dap)2 ] Cl或[Cu(dap)Cl 2 ]对于这种转化是独特的,这归因于它们与金属,金属或金属的相互作用。底物通过配体交换和反弹机制。有人建议将铜II作为催化活性物质,将其与叠氮化物配位后将进行光加速均质分解,从而形成铜I和叠氮化物自由基。这种激活原则(CU II -X→铜我+ X 。)开启了铜基光催化的新途径。

4-phenyl-N-(phenyl)thiazol-2-amine and 4-(pyridin-3-yl)-N-( phenyl) thiazol-2-amine derivatives and the corresponding thiadiazole, thiophene, oxazole, oxadiazole, imidazole and triazole derivatives and related compounds as aryl hydrocarbon receptor (AHR) agonists for the treatment of angiogenesis implicated disorders, such as e.g. retinopathy, psoriasis, rheumatoid arthritis, obesity and cancer, or inflammatory disorders.
In the present study, a series of dibenzoazepine triazole derivatives (24-39)
were synthesized and evaluated for their in vitro bioactivities including antiglycation,
antibacterial, DPPH radical scavenging, urease inhibition, antileishmanial and immunomodulatory
activities. The compounds were found to be moderately active only
against leishmania. Within this series, compound 26 was found to be the most active
antileishaminals with IC50 value 37.4 ± 0.4 µM. Structure-activity relationships for
this novel class are discussed.
A novel imidazolium-based ionic liquid-supported hypervalent iodine reagent has been synthesized and employed for a âcatch and releaseâ strategy with substituted acetophenones to generate various α-substituted acetophenones in good to excellent yields. The use of an ionic liquid-supported hypervalent iodine reagent avoids chromatographic separation for the purification of α-substituted acetophenones and thus makes the method greener.
