Notes:
An unambiguous structural differentiation of B/C-cis- and B/C-trans-morphinan derivatives (thebainone-A and β-thebainone-A and their 7,8-dihydro derivatives) is provided. The structures were confirmed by NOE difference spectroscopy and selective 2D J-INEPT experiments. In addition, full a priori 1H and 13C NMR assignments of the isomeric pairs studied are presented.
