DMP-mediated one-pot oxidative olefination of silyl ethers

Silyl ethers of arylic, allylic, propargylic and unactivated alcohols could be deprotected and oxidized with Dess–Martin periodinane, and the resulting aldehydes could be directly converted to the corresponding α,β-unsaturated esters in one pot with stabilized phosphoranes. Good selectivities were achieved upon a variety of protecting groups of alcohol by using this method. Other advantages of the protocol included simplicity of operations and high efficiency, as well as good to excellent yields.
