摘要

Some 8-substituted derivatives of the protoberberine alkaloids palmatine (1a) and berberine (1b) have been prepared and investigated by 1D and 2D NMR spectroscopy (H-1, C-13, N- 15). Complete NMR data for the 8-hydroxy (2), 8-methoxy (3), 8-ethoxy (4), and 8- trichloromethyl (5) 7, 8-dihydro derivatives of 1a and 1b, as well as X-ray data for 8- methoxydihydroberberine (3b), 8-trichloromethyldihydropalmatine (5a), and 8- ...
