Abstract: A chemoselective, solvent-free, mild and efficient method for the synthesis of acylals and their deprotection to 4-oxo-4H-1-benzopyran-3-carbaldehydes catalyzed by ceric ammonium nitrate (CAN) are carried out in good yields and all compounds 2a-h are characterized by IR, 1H NMR and 13C NMR spectral data.
