(R)-p-bromostyrene oxide. The exocyclic positions opened the epoxide at the alpha-carbon. Epoxide ringopening by the nitrogen at the 7-position showed little preference for the alpha- or beta-carbons in reactions with p-methylstyrene oxide. However, the p-bromostyrene oxide favored reaction at the beta-carbon almost 4-fold over reaction at the alpha-carbon. Almost total inversion of stereochemistry was found
