In a cheap and eco-friendly process, primary and secondary alcohols were easily protected as bis(methoxyphenyl)methyl (BMPM) ethers in good yields using CuBr2 as a catalyst in acetonitrile at room temperature. Deprotection could easily be achieved using the same catalyst but in ethanol. Both Cu-catalyzed protection and deprotection were orthogonal to other methods and fully compatible with other functional
在便宜且环保的过程中,使用CuBr 2作为
乙腈催化剂在室温下,伯醇和仲醇很容易以高收率得到保护,成为双(
甲氧基苯基)甲基(
BMPM)醚。使用相同的催化剂但在
乙醇中可以轻松实现脱保护。
铜催化的保护和脱保护均与其他方法正交,并且与其他官能团完全相容。
