Abstract

An acid- and base-stable protecting group for carboxylic acids is described. The esters of (2,6-dichloro-4-methoxyphenyl)(2,4-dichlorophenyl) methanol are stable to Bransted and Lewis acids, Brønsted bases, and a wide variety of nucleophiles; however, the esters can be conveniently deprotected by a solvolytic displacement reaction with 20% trifluoroacetic acid.
