The reaction of β-amino ketones with bis(acetonitrile)dichloropalladium(II) in the presence of triethylamine gives the corresponding enaminones regioselectively. The cyclic β-amino ketones can be converted into the corresponding exocyclic enaminones. The enaminones thus obtained are versatile synthetic intermediates. The reaction of (E)-enaminones with organocuprates gave the corresponding (E)-α,β-unsaturated ketones.
在
三乙胺存在下,β-
氨基酮与双(
乙腈)二
氯钯(II)反应,选择性地生成相应的烯胺酮。环状β-
氨基酮可以转化为相应的开链烯胺酮。由此得到的烯胺酮是多用途的合成中间体。(E)-烯胺酮与
有机铜酸盐反应,得到相应的(E)-α,β-不饱和酮。
