α-Trifluoromethyl allenol ethers 9a-e were prepared in moderate to good yields by the Julia-Lythgoe process using β-ethoxy-β-trifluoromethyl vinylic sulfone 3. Several reactions of 9c were examined to give α, β-unsaturated trifluoromethyl ketone derivatives 11 and 12.
α-三氟甲基丙焰醇醚 9a-e 是通过使用 β-乙氧基-β-三氟甲基烯基磺酸酯 3 的 Julia-Lythgoe 反应以中等到良好的产率制备的。对 9c 进行了几种反应,以获得 α, β-不饱和三氟甲基酮衍生物 11 和 12。
