A Mild and Efficient Method for the Cleavage of tert-Butyldimethylsilyl and Tetrahydropyranyl Ethers by Ceric Ammonium Nitrate in Methanol

Abstract
A variety of tert-butyldimethylsilyl (TBDMS) and tetrahydropyranyl (TFP) ethers were cleaved with ceric ammonium nitrate in methanol at 0 °C in short time. It has been shown that the reaction is chemoselective in a few cases. The primary TBDMS ethers have been cleaved selectively in the presence of THP ether and ketal.
