New aporphine-benzylisoquinolines are (+ )-thalipine (51), present in Thalictrum polygamum Muhl. (Ranunculaceae)58 and in R. revolution DC,59 and ( + )-rev-olutopine (53), found in the latter plant.59... [Pg.132]

Occurrence Thalictrum longistylum (62), Thalictrum longepedunculatum (63), Thalictrum lucidum (64), Thaiictrum minus (59,65,66), Thalictrum polygamum (64), Thalictrum podocarpum (61), Thalictrum revolutum (6S), Thalictrum rugosum (69)... [Pg.111]

Two new aporphine-benzylisoquinoline dimers from Thalictrum polygamum Muhl. are pennsylvanine (46) and pennsylvanamine (47). [Pg.179]

A continuing investigation of the alkaloids of Thalictrum polygamum Muhl. has resulted in the isolation of members of an interesting and novel isoquinoline group, the aporphine-pavine dimers. Pennsylpavine (59) and pennsylpavoline (60) are weakly basic phenolic alkaloids which are accompanied in the plant by the aporphine-benzylisoquinolines pennsylvanine (46) and pennsylvanamine (47). It therefore seems likely that (46) and (47) are biogenetic precursors for (59) and (60), respectively. ... [Pg.181]

The two dimeric pavine alkaloids (pennsylpavine and pennsylpavoline) were isolated from Thalictrum polygamum (565). [Pg.433]

New benzylisoquinoline alkaloids are (+ )-iV-norprotosinomenine (14), found in Erythrina lithosperma Blume (Leguminosae), and A-methylpalaudinium chloride (15), isolated from Thalictrum polygamum Muhl. (Ranunculaceae). ... [Pg.119]

The possible origin of the methylenoxy bridge in thalphenine has been discussed. (H-)-Nantenine methochloride has been found to accompany thalphenine (11) in Thalictrum polygamum Muhl. (Ranunculaceae). Assuming an... [Pg.149]

A strongly levorotatory alkaloid isolated from Thalictrum dioicum by Shamma and co-workers (82) was named (-)-thalidine (21) and assigned an isopavine structure on the basis of mass spectral analysis. The diphenolic nature of the alkaloid was evidenced by H-NMR data and by the bathochromic shift in the UV spectrum on addition of alkali. Diazomethane 0-methylation produced (—)-thalisopavine (30) and (—)-0-methylthalisopavine (26). Of the two probable isomeric structures, 21 and 22, 21 was slightly favored on biosynthetic grounds. Final proof to structure was provided by total synthesis (82). (—)-Thalidine has also been reported from T. polygamum (83). [Pg.328]
