Abstract

When subjected to ordinary Koch-Haaf carboxylation conditions the tertiary alcohol, 2-(1- adamantyl)-2-propanol (4) yields only the rearranged carboxylic acid, 3-isopropyl-1- adamantane carboxylic acid (5). Mechanistic evidence is presented which indicates that the rearrangement proceeds via intermolecular hydride shifts. A variety of synthetic approaches to the unrearranged 2-(1-adamantyl)-2-methylpropionic acid (1) are described, and the ...
