Summary

IR-spectra of lactamides of 1,4-tomatadien-3-one (5), 4-solasoden-3-one (7), dihydrotomatidine (8) and tomatine (6) were taken and the frequency of the C=O amide band compared with that of the lactamides of piperidine (1) and its derivatives and N-acetyl tomatidine (9). It was found that the C=O band of lactamides of steroidal alkaloids show an unusual but characteristic frequency at 1730–1733 cm−1.
