(Z)-Silyl enolethers can be prepared selectively with complete regio-specificity by treating 1-trimethylsilylallylicalcohols with a catalytic amount of butyllithium.
The isomerization of an α-trimethylsilyl ketone is lead to the corresponding trimethylsilyl enolether with the enhanced regioselectivity by heating or by the assist of trimethylsilyl trifluoromethanesulfonate. The thermal reaction discloses a new regiodefined (E)-selective route to silyl enolethers.
