Monovalent phenolsQ 0180 LiOAc-Catalyzed Chemoselective Deprotection of Aryl Silyl Ethers under Mild
Conditions. — Phenolic Tbs, Tes, and Tps groups can be removed efficiently and se-lectively. Aliphatic silyl ethers, phenolic acetates, carbamates and epoxides are not at-tacked. The Tbs moiety reacts faster compared to Tps, thus allowing a chemoselective deprotection. The method can also be applied to the enol ether (VI). — (WANG*, B.; SUN, H.-X.; SUN, Z.-H.; J. Org.
