A cyclobutane tricarboxylic acid is the central element in the structure of grahamine 1 , a tropane alkaloid found in the Chilean nightshade Schizanthus grahamii . Two of the carboxylic acid functions are incorporated into a macrocyclic tetraester moiety. The overall structure of 1 was elucidated using a combination of 1 H‐ and 13 C‐NMR techniques.
