The 7,8-methylenedioxyhydroxyisopropyldihydrofuroquinolone alkaloid, (-)-hydroxylunine (55), was isolated from Lunasia amara (Volume IX, p. 245), and the (+) enantiomer has now been shown to be a constituent of Ptelea trifoliata (55). Mitscher et al. (54) obtained the corresponding quaternary salt, O-methylhydroxyluninium salt (56), from the stems of... [Pg.121]

Another apparent anomaly arises from the assignment of an (5) configuration (54) to (—)-0-methylhydroxyluninium salt (120) by comparison of the circular dichroism spectrum with (+)-(/ )-pteleatinium salt (102) these alkaloids cooccur in Ptelea trifoliata, and the stereochemical result implies that they are derived biosynthetically from epoxides of opposite configuration. [Pg.135]
