Abstract
Both cyclic and acyclic acetals were deprotected to give the corresponding aldehydes in acetonitrile, and are transformed to methyl esters in methanol, on treatment with a catalytic quantity of V2O5 and H2O2. Under identical conditions acid-sensitive alcohol protecting groups, such as tetrahydropyranyl and tert-butyldimethylsilyl ethers, were cleaved regenerating the corresponding alcohols.
