Pachygone ovata

Details of the isolation of the title alkaloids from Pachygone ovata have been published. The ceric ammonium nitrate degradation of /V. O-dimethyltiliamosine (351) is described for the first time (547). O-Acetyltiliacorinine has been found to have [oc]g,7 +290° (c 0.41, pyridine), rather than the higher value previously reported (547). [Pg.176]

Nortrilobine (500), C34H32N205, mp 177-180°C (MeOH), [a] 5 +216° (c 0.44, CHC13), from Pachygone ovata Miers ex Hook. f. Thoms. (Menispermaceae), is the first bis-secondary dibenzo-p-dioxin bisbenzylisoquinoline alkaloid. It was examined by... [Pg.188]

Pronuciferine (1) has been synthesized by photocyclization of the brominated phenol (2).9a The light-induced rearrangement of proaporphines yields aporphines that are substituted at C-9 or at both C-8 and C-9.5 This topic is further discussed below, under the sections on aporphines and aporphine dimers. The known alkaloid N-methylcrotsparine has been found in Pachygone ovata.9b... [Pg.117]

There are three alkaloids in this group, each of which bears a C(5) methoxy group, and is phenolic at C(12 ). The stereochemistry of the chiral centers at N(2) and N(2 ) is unknown. Tiliamosine (120) has been isolated from both Pachygone ovata (Menispermaceae) and Tiliacora racemosa (Menispermaceae), while pachygonamine (249) and N-methylpachygonamine (243) have only been isolated from the former plant.
