The rare alkaloid casimiroedine and its peracetylated derivative both show complex 1 H and 13 C spectra with almost all signals doubled owing to slow rotation about the amide bond. Nevertheless, it is possible, using 2D NMR methods, to assign fully the 1 H and 13 C spectra of the major and minor conformational isomers for each compound. Copyright © 2000 John Wiley & Sons, Ltd.
