The synthesis and NMR elucidation of five novel penta‐cycloundecane amine derivatives are reported. These compounds are potential antituberculosis agents. The 1 H and 13 C spectra showed major overlapping of methine signals of the cage skeleton making it extremely difficult to elucidate these compounds. The overlapping occurs as a result of the additions made to the carbonyl carbon (C‐8/C‐11) of the cage. The two‐dimensional NMR technique proved to be a useful tool in overcoming this problem. All compounds reported are meso compounds thereby not only simplifying the NMR structure elucidation, but also making it indeed possible. Copyright © 2008 John Wiley & Sons, Ltd.
