Abstract

Ketene silyl acetals are frequently employed in organic synthesis as isolable ester enolate equivalents. These reagents are advantageous because they are easy to prepare and they exhibit higher reactivities toward electrophiles than the corresponding silyl enol ethers derived from ketones or thio esters.'Mukaiyama and Ishida reported the reaction of silyl dienol ethers with various electrophiles to afford the products resulting from attack at the y- ...
