Ketoxime anions 2, generated from the corresponding ketoximes 1 and sodium hydride, were reacted with α-ethoxycarbonyl vinylphosphonate 3 to give the phosphoryl-stabilized carbanions 4 which were further reacted with aldehydes affording ethoxycarbonyl allyl substituted oxime ethers in 73-91% yields.
由相应的酮肟 1 和氢化钠生成的酮肟阴离子 2 与δ-乙氧羰基乙烯基膦酸盐 3 反应,得到磷酰稳定的碳阴离子 4,再与醛反应,得到乙氧羰基烯丙基取代的肟醚,产率为 73-91%。
