LiOAc-catalyzed chemoselective deprotection of aryl silyl ethers under mild conditions

, : LiOAc-catalyzed chemoselective deprotection of aryl silyl ethers under mild conditions. Journal of Organic Chemistry 74(4): 1781-1784

An efficient and chemoselective deprotection protocol for aryl silyl ethers using LiOAc as a bifunctional Lewis acid-Lewis base catalyst was described. Acetates, epoxides, and aliphatic silyl ethers were preserved, whereas aryl TBS and TBDPS ethers can be differentiated.
