Base-induced rearrangement of 1-(trimethylsilyl)allylic alcohols. Stereo- and regioselective synthesis of silyl enol ethers through lithium homoenolates
The palladium catalyzed cross-coupling reaction of thiolesters with bis(iodozincio)methane or 1,1-bis(iodozincio)ethane gave Reformatsky-type enolates. They can react with some electrophiles to give the corresponding adducts and were also trapped by silylation reagents to afford silyl enol ethers. As the method applicable to the thiolester carrying ketone moiety, it afforded zinc enolates carrying
