The Synthesis of <I>endo</I>-5-(4-imidazolyl)bicyclo[2.2.2]oct-<I>endo</I>- and <I>exo</I>-2-yl <I>trans</I>-cinnamates was carried out starting from 2-butyn-1,4-diol. The key intermediate, <I>endo</I>-5-(4-imidazolyl)bicyclo[2.2.2]octan-2-one, was obtained by oxidation of <I>endo</I>-5-(4-imidazolyl)bicyclo[2.2.2]oct-2-ene with palladium chloride, the oxidation being stereo- and regiospecific. The mode of 2,5 disubstitution and endo, exo stereochemistry were determined by means of <SUP>13</SUP>C chemical shifts of the bicyclo[2.2.2]octane framework.
