| 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. |
