Description

We have investigated a new mild deprotective method for various O-allylphenols to give the corresponding phenols. The reaction of O-allylphenols bearing electron-withdrawing and weak electron-donating groups on the benzene ring proceeded smoothly, whereas the reaction of O-allylphenols having strong electron-donating groups gave phenols in nil to moderate yields. Mono-deprotection of O,O'-diallylcatechols was proceeded successfully to afford the corresponding O-allyloxyphenols. Moreover, we revealed that the present reaction proceeded via the SET process. Because 10% Pd/C is a heterogeneous catalyst, the deprotected phenol was obtained in essentially pure form by simple filtration and extraction procedure.
