Summary
1. The trans-linkage of rings A/B in compounds (I-III) and of rings B/C and E/F in veralodine and the equatorial orientation of the OH group at C3 in isogermine has been confirmed by CD spectroscopy.
2. A relationship has been established between the nature of the substituents and the configurations at C20 and the sign of the CE in the 200 nm region for compounds (I-III).
3. The 22R configuration has been established for veralomidine.
