摘要：
Ti-HMS, a TI-loaded hexagonal mesoporous silica, was found to accelerate deprotection of benzyl ethers under hydrogenolytic conditions with palladium catalyst. Such acid-sensitive functional groups as silyl ether and acetal moieties in the molecule were little affected by Ti-HMS, which possesses Lewis acid sites due to Ti-atom.
