  • compound
  • The compound 3 , which exists in tautomeric equilibria between enamine (form A) and methylene imine (form B), was prepared by addition of ethoxycarbonylmethyl chloride 2 (1.23g, 0.01 mol) to a solution of 3-(ethoxycarbonylmethylene)-2-oxo quinoxaline, 1 (2.32 g, 0.01 mol) in 60 ml DMF, K 2 CO 3 (1.38g, 0.01mol) and triethylbenzylammonium chloride (0.001 mol).

  • BMS-345541, marketed by Merck KGaA, is an anti-inflammatory, cell-permeable quinoxaline compound. (wikipedia.org)
  • group
  • The parent substance of the group, quinoxaline, results when glyoxal is condensed with 1,2-diaminobenzene. (wikipedia.org)
  • In contrast to previously employed directing groups, quinoxaline is an integrated directing group in the final product that only promotes ortho -mono-arylation without the formation of bis-arylated products. (rsc.org)
  • groups
  • The designed quinoxalines were substituted for the dodecyloxy groups on the benzene ring and stillbene groups were attached by knoevenagel reaction or Hornor-Wadsworth-Emmons (HWE) reaction on the 2,3-positions of the pyrazine ring. (ingentaconnect.com)
  • study
  • One study used 2-iodoxybenzoic acid (IBX) as a catalyst in the reaction of benzil with 1,2-diaminobenzene: Pyrazinamide and Morinamide are made out of quinoxaline. (wikipedia.org)
