✦ Synopsis

The regiochemistry of the acylation of enol ethers, generated in situ, from acetals of unsymmetrical ketones is reported. These results demonstrate a convenient one-pot method to obtain a series of I~-methoxyvinyi trichloromethyl ketones [CCI3COCH=C(OMe)R, where R=Et, n-Bu, i-Pr, (CH2)2C(OMe)=CHC(O)CCI3 and (CH2)sCOeCH3)] in high yields.
