| Abstract: | Catalytic deprotection of various protected alcohols was efficiently conducted using a hydrophobic low-loading and alkylated polystyrene-supported sulfonic acid (LL-ALPS-SO3H) in water as the sole solvent. Transprotection of an alcohol from a silyl ether to the corresponding benzylic ether or ester also proceeded smoothly in water. |
