Two new alkaloids were extracted from the bark of Ancistrocladus tectorius, 6,8-dimethoxy-3-hydroxymethyl-1-methylisoquinoline and the naphthylisoquinoline, 4′-O-demethylancistrocladine, together with the known isoquinolines, 6,8-dimethoxy-1,3-dimethylisoquinoline and (S)-6,8-dimethoxy-1,3-dimethyl-3,4-dihydroisoquinoline, which, however, have never been isolated from a natural source. The structures of the new alkaloids, as well as the absolute stereochemistry of 4′-O-demethylancistrocladine were established by spectroscopic means and chemical correlations.
