(Z)-Silyl enolethers can be prepared selectively with complete regio-specificity by treating 1-trimethylsilylallylicalcohols with a catalytic amount of butyllithium.
Base-induced rearrangement of 1-(trimethylsilyl)allylic alcohols. Stereo- and regioselective synthesis of silyl enol ethers through lithium homoenolates
(Z)-trimethylsilyl enol ethers with dibutylboryl trifluoromethanesulfonate followed by removal of trimethylsilyl triflate generated and addition of aldehydes affords the corresponding erythro aldols with almost complete stereo- and regio-selectivities.
