A new set of highly substituted pyridine derivatives has been synthesized by a product selective four component reaction of aryl aldehyde, malononitrile and 2-aryl/cyclohexylsulfanyl-1-aryl-1-ethanones in presence of sodium hydroxide in methyl/ethyl alcohol. Among the compounds, 4,6-bis(4-chlorophenyl)-5-[(4-chlorophenyl)sulfanyl]-2-methoxynicotinonitrile (4n) inhibited Mycobacterium tuberculosis (MTB)
通过在甲醇/乙醇中存在氢氧化钠的情况下,通过芳基醛,丙二腈和2-芳基/环己基硫烷基-1-芳基-乙酮的产物选择性四组分反应合成了一组新的高度取代的吡啶衍生物。在这些化合物中,4,6-双(4-氯苯基)-5-[(4-氯苯基)硫烷基] -2-甲氧基烟腈(4n)抑制结核分枝杆菌(MTB)的最小抑制浓度(MIC)为3.1μM,为比乙胺丁醇和吡嗪酰胺更有效。
