Reaction of alcohols with dihydropyran in the presence of a catalytic amount of Sc(OTf)3 provides efficiently the corresponding tetrahydropyranyl ethers. After the reaction, the catalyst can be recovered quantitatively from the aqueous media and reused without loss of the activity.

Direct conversion of alcohol silyl ethers into the corresponding tetrahydropyranyl (THP) ethers can be easily performed by reaction with THP acetate under the influence of a catalytic amount of tert-butyldimethylsilyl trifluoromethanesulfonate (TB-SOTf). Aliphatic TBS ether can be selectively transformed into the corresponding THP ether in the presence of phenolic TBS ether.

Alcohols and phenols are tetrahydropyranylated rapidly in high yields in the presence of catalytic amount of iodine at room temperature. Depyranylation is effected readily by refluxing with iodine in methanol for few hours.
