N2 - Some 8-substituted derivatives of the protoberberine alkaloids palmatine and berberine have been prepared and investigated by 1D and 2D NMR spectroscopy (H-1, C-13, N-15). Complete NMR data for the 8-hydroxy-, 8-methoxy-, 8-ethoxy-, and 8-trichloromethyl-7,8-dihydro derivatives of palmatine and berberine, as well as X-ray data for 8-methoxydihydroberberine, 8-trichloromethyldihydropalmatine, and 8-trichloromethyldihydroberberine are presented. The physicochemical data for all of these compounds are reviewed and compared with previously published values.
