Asymmetric Hydrogenation and Catalysis

Abstract Acetalization of aldehydes using a new silica‐supported molybdenum(VI) oxide (20%) catalyst has been explored. Additionally, facile deprotection strategy for the acetals is reported including the results from the replacement of solvent studies. The protocol achieved the protection O,O‐acetals in excellent yield within a few hours under neutral conditions and also deprotection of aromatic O,O‐acetals in excellent yields was achieved within a few minutes in aqueous acetone.
