Silver(I)-Catalyzed Deprotection of p-Methoxybenzyl Ethers: A Mild and Chemoselective Method
摘要:
The p-methoxybenzyl protecting group (PMB) on various alcohols and an acid was efficiently and selectively, cleaved by the action of a catalytic amount of silver(I) hexafluoroantimonate combined with 0.5 equiv of 1,3,5-trimethoxybenzene in dichloromethane at 40 degrees C.
