A convenient two-step synthesis of 4-CF3-(2H)-pyridazin-3-ones starting from methyl 3,3,3-trifluoropyruvate (MeTFP) and carbonyl compounds has been elaborated. As a result, a set of various 4-CF3-(2H)-pyridazin-3-ones was obtained. The scope and limitations of the methodology is defined.
以 3,3,3-
三氟丙酮酸甲酯(Me
TFP)和羰基化合物为起点,精心设计了一种简便的两步法合成 4-
CF3-(2H)-pyridazin-3-ones 的方法。结果得到了一组不同的 4- -(2H)-pyridazin-3-ones 物。界定了该方法的范围和局限性。
