The stereochemistry of berbines (1-15) and their berbane (16) and berbinanes (17 and 18) derivatives was established on the basis of their ir, 1H-nmr, 13C-nmr spectral data and the rates of methiodide formation. All the compounds in this study were found to have a trans-B/C conformation whereas berbinane (18) had a cis-A/B configuration.
