Abstract

An efficient protocol for the preparation of MOM ethers from alcohols and formaldehyde dimethyl acetal (DMFA) using ZrCl4 (10mol%) at room temperature under solvent free conditions has been developed. Similarly, the same Lewis acid, ZrCl4 (50mol%), in isopropanol at reflux was utilised for the deprotection of MOM ethers.
