A three new series of the ferrocene containing quinolines – 2-ferrocenyl-4-methoxyquinolines, 1-benzyl-2-ferrocenyl-2,3-dihydroquinolin-4(1H)-ones and 1-benzyl-2-ferrocenylquinolin-4(1H)-ones – were synthesized in order to test their in vitro antimicrobial activity against six strains of bacteria and one fungal/yeast strain. It has been shown that all 21 quinolines are completely inactive against the
This work describes an effective C3–H halogenation of quinoline-4(1H)-ones under electrochemical conditions, in which potassium halides serve as both halogenating agents and electrolytes. The protocol provides expedient access to different halogenated quinoline-4(1H)-ones with unique regioselectivity, broad substrate scope, and gram-scale synthesis employing convenient, environmentally friendly electrolysis

An efficient electrochemical approach for the synthesis of 4-quinolones via intramolecularC(sp3)–H/C(sp3)–H cross-coupling has been developed under metal- and external oxidant-free conditions. This electrochemical approach provides a simple and efficient route to construct useful 4-quinolone derivatives in moderate to good yields.

An efficient and divergent synthesis of N-arylbenzimidazoles and N-arylindazoles from arylamino oximes based on reaction conditions selection was developed. The synthesis was approached by treating oximes with BTC and the chemoselectivity was regulated by the amount of Et3N. This switchable N-N and N-C bond formation process features mild reaction conditions, simple execution, high chemoselectivity and broad substrate scope. (C) 2020 Elsevier Ltd. All rights reserved.
