An efficient and selective method was developed for the deprotection of triethylsilyl (TES) ethers using formic acid in methanol (5-10%) or in methylene chloride 2-5%) with excellent yields. TES ethers are selectively deprotected to the corresponding alcohols in high yields using formic acid in methanol under mild reaction conditions. Other hydroxyl protecting groups like t-butyldimethylsilyl (TBDMS) remain unaffected.
开发了一种高效且选择性的方法，用于使用甲醇（5 - 10%）或二氯甲烷（2 - 5%）中的甲酸对三乙基硅基（TES）醚进行脱保护，产率优异。在温和的反应条件下，使用甲醇中的甲酸可将TES醚选择性地高产率脱保护为相应的醇。其他羟基保护基团如叔丁基二甲基硅基（TBDMS）不受影响。
