Two Methods for Selective Deprotection of Diphenylmethylsilyl Protecting Group under Aqueous Conditions
By

Two, new, methods for chemo-selective deprotection of diphenylmethylsilylether of allylic, benzylic, and alkyl alcohols is achieved. Catalytic amounts of Perfluoro-1-butanesulfonyl fluoride or stoichiometric amounts of 18-crown-6 ether are employed for successful deprotection. All selective deprotection can be attained under mild aqueous conditions.
