| 2 | Selective cleavage of phenolic tert-butyldimethylsilyl ethers using simple organic nitrogen bases显示文摘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 efficiency of these bases has an apparent 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 ... | Zhu, Jian Rong Xue, Ji Jun Lib, Wen Ze Chen, Xue Song Li, Ying | 2010 | Chinese Chemical Letters2010，21，3： | 0 |
