摘要
Different types of alcohols and phenols were effectively converted to the corresponding THP ethers in the presence of DHP and a catalytic amount Of lithium trifluoromethanesulfonate (LiOTf) in refluxing 1,2-dichloroethane under essentially neutral reaction conditions. The method also shoals good chemoselectivity For mono-tetrahydropyranylation of symmetrical diols. (C) 2002 Elsevier Science Ltd. All rights reserved.
