A new reagent for the deprotection of aromatic methyl ethers, 2-(diethylamino)ethanethiol, is reported. This compound, commercially available as its HCl salt, affords the corresponding phenols in good to excellent yields on a wide variety of substrates. A clear advantage of this method over the use of more common thiols, such as ethanethiol, is the easy extraction of both the deprotecting reagent and
报道了一种用于芳族甲基醚的脱保护的新试剂2-(二乙基氨基)乙硫醇。这种化合物以其HCl盐的形式商购可得,可在多种底物上以高至极好的收率提供相应的酚。与使用更常见的硫醇(如乙硫醇)相比,此方法的明显优势在于,通过用稀酸淬灭,可以轻松地将脱保护剂和副产物2-(二乙氨基)乙基甲基硫化物萃取到水相中,从而实现基本上无味的处理。
