N-Cbz- and N-Boc-protected exo-spiro[oxirane-3,2′-tropanes] were obtained in 62–75% yield via either epoxidation or hydroxybromination/dehydrobromination of the corresponding alkenes. Deprotection of the Cbz-exo-epoxide afforded the corresponding tropane containing an exo-oxirane fragment and a secondary amino group.
