The naming system reflects the origins of the steroidal units: 'Ornitho' from Ornithogalum saundersiae, 'statin' from cephalostatin and 'ritter' or 'zine' from ritterazine, in keeping with the system adopted for the earlier hybrid ritterostatins (ref 6).

The NMR of 8a showed a single diastereomer and was consistent with that of related 22S compounds. The 22S configuration was also calculated to be 2.2 kcal/mol more stable than the 22R epimer (CAChe v.3.5).

note

Conceivably, protonation of the 16αOH in 11 or 12 and β face attack by ketal or ketone oxygen could lead to a hemiketal and an E-ring oxocarbenium ion. However, we have observed no evidence for such reaction in either 12 nor 20 upon standing in acidic chloroform.
