Simple

organic

nitrogen

bases,such

as

Et_3N,pyridine,DBU,etc.,were found to be convenient and useful reagents for deprotection of TBDMS groups on acidic hydroxyl groups.The

of

these

bases

has

an

order:1°amine>2°amine>3°amine and aliphatic base>aromatic base.In aqueous DMSO and at room temperature,phenolic TBDMS ethers were removed selectively in the presence of alcoholic TBDMS ethers.And catalytic base can make these reactions complete.This method is high-yielding,fast,clean,safe and ... 【总页数】1页(P.) 【关键词】 【作者】无 【作者单位】 【正文语种】英文 【中图分类】O621.3 【相关文献】
