Abstract

Catalytic amount of Ce(IV) as ceric triethylammonium nitrate (CTEAN) in dichloromethane or acetone can bring about an efficient tetrahydropyranylation of different types of alcohols to afford the corrsesponding tetrahydropyranyl ethers in high yields. Deportection of tetrahydropyranyl ethers can also be achieved efficiently in the presence of this catalyst in methanol.
