Chemoselective Tetrahydropyranylation of Alcohols and Their Detetrahydropyranylation Using Silicasulphuric Acid as a Reusable Catalyst

摘要

A simple,mild,and efficient protocol for chemoselective protection of alcohols over phenols as tetrahydropyranyl ethers and their deprotection using silicasulphuric acid as a reusable solid acid catalyst is described.
