356	Trifluoroacetic acid catalyzed tetrahydropyranylation of alcohols and phenols and direct conversion of THP ethers into acetates		An expedite and convenient procedure for tetrahydropyranylation of alcohols and phenols in dichloromethane and their depyranylation in methanol in the presence of trifluoroacetic acid at ambient temperature is developed. The reaction conditions are tolerable for a variety of functionalities. The direct conversion of tetrahydropyranyl ethers into their corresponding acetates under trifluoroacetic acid catalysis is also achieved.
