Abstract

The reaction of isomeric hydroxypyridines with 1-bromoadamantane under various conditions led to mono- and disubstituted С-, О-, and N-adamantylation products. Hydroxypyridines and 4-dimethyl-aminopyridine were found to have catalytic effect on the quaternization of pyridine with adamantyl bromide. A method was developed for the preparation of quaternary 1-(adamant-1-yl)pyridinium salts under mild conditions.
