First synthesis of a alpha-trifluoromethyl allenol ether via the Julia-Lythgoe process.
Alpha-trifluoromethyl allenol ethers 9a-e were prepared in moderate to good yields by the Julia-Lythgoe process using beta-ethoxy-beta-trifluoromethyl vinylic sulfone 3. Several reactions of 9c were examined to give alpha,beta-unsaturated trifluoromethyl ketone derivatives 11 and 12.
