Chloro-, hydroxy-, methoxy-, and tert-butyl-substituted 3-carboxycoumarins have been prepared by one-pot procedure by reaction of suitably substituted salicylaldehydes with malononitrile in water. The over-all yields are high and the protocol does not require organic solvents.
通过一步法,将适当取代的水杨醛与丙二腈在水中反应,成功制备了氯代、羟基、甲氧基和叔丁基取代的3-羧基香豆素。总体产率较高,且该方法无需使用有机溶剂。
