摘要：
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.
