ChemInform Abstract
Catalytic iodine in methanol is a well-known reagent for the deprotection of acetals. During a preparation in which the removal of an isopropylidene group in the presence of a Pmb ether is required, a simultaneous cleavage of the Pmb ether is discovered. The finding is evaluated to a simple selective method for the deprotection of a variety of Pmb ethers, even in the presence of benzyl ethers.
