New salicyl alcohol derived photolabilecarbonylprotectinggroups have been developed, and the effect of substituents on the photochemical properties of photolabileprotectinggroups (PPGs) has been studied. The 3-(dimethylamino)phenyl groups at the α position prove to be important to the efficiency of the deprotection reactions, as shown in the photo reactions of the acetal 9. On the other hand,
