Selective Deprotection of the Diphenylmethylsilyl (DPMS) Hydroxyl Protecting Group Under Environmentally Responsible, Aqueous Conditions

Abstract

Two new methods for deprotection of diphenylmethylsilyl (DPMS) ethers are described. Selective unmasking can be achieved with either catalytic amounts of perfluoro‐1‐butanesulfonyl fluoride (a SuFEx reagent) under mild, aqueous micellar conditions, or using stoichiometric amounts of 18‐crown‐6 ether in aqueous ethanol.
