Fluoromethyl ketone enol ethers are regiospecifically prepared in good yields by treatment of 2-alkoxy-1,3-bis(t-butyldimethylsiloxy)alkane with TBAF-MsF, and subsequent thermal [3,3]-sigmatropic rearrangement on the 2-alkenyl enol ethers gives α-allylated products.
通过用TBAF-MsF处理2-烷氧基-1,3-双(叔丁基二甲基甲硅烷氧基)烷烃,然后在2-烯基烯醇上进行热[3,3]-σ重排,可以区域特异性地制备高产率的氟甲基酮烯醇醚。醚产生α-烯丙基化产物。
