A convenient method for the synthesis of N-arylisatins from 2-(arylamino)acetophenones by using SeO2 as an oxidant is described. Various substituted N-arylisatins were selectively obtained in good to excellent yields. The reaction tolerates a wide range of functionalities.
3-b]quinolines. Separate cyclization was also performed under acidic conditions on 2-(arylamino)phenones in order to obtain acridines and related compounds. Most of the synthesized compounds were screened for their antiproliferative activity in A2058 melanoma cells, and against a panel of disease-relevant kinases such as mammalian CDK5/p25, PIM1, CLK1, DYRK1A, GSK3α/β, Haspin and leishmanial CK1.

The study reports selective electrochemical synthesis of 1H-indazoles and N-oxides, where electrochemical outcomes were dictated by the cathode material (RVC=reticulated vitreous carbon). The adaptability of 1H-indazole N-oxides for various C−H functionalization reactions was showcased. Furthermore, 1H-indazole N-oxides were utilized to synthesize the pharmaceutical molecules lificiguat and YD (3)
该研究报告了 1 H-吲唑和N-氧化物的选择性电化学合成,其中电化学结果由阴极材料决定(RVC=网状玻璃碳)。展示了1 H -吲唑N -氧化物对各种 C−H 官能化反应的适应性。此外,1 H -吲唑N -氧化物被用于合成药物分子 lificiguat 和 YD (3),各种药物的关键中间体,以及有机发光二极管的前体。
