Daphnandra

DAPHNANDRA spp. Bancroft recorded the presence of alkaloids in several Daphnandra species, notably D. repandula and D. micrantha. The latter was examined by Pyman and shown to contain three alkaloids, daphnandrine, micranthine and daphnoline. [Pg.326]

Several collections tested in this study were known to contain alkaloids Daphnandra diets ii (2/2), D. lenuipes, Doryphora aro-matica, D. sassafras, Dryadodaphne novoguinense, Laurelia novo-zealandiae (8/8), Palmeria arfakiana (2/2), P. fengeriana, Siparuna guianensis (4/5). [Pg.143]

The orange-yellow alkaloid daphnine (113) was isolated from Daphnandra repandula (66). The structure was proven by NOEDS studies (see Section VI,A,2,b) of its dihydro diacetate in CD3C02D. These measurements showed the connectivity relationships of 2 -Me-3 -H-4 -H-5 -H-6 -OMe and 5-H-6-OMe, which served to eliminate other isomeric structures, notably a 7-6 ether-linked dimer (67). The structure of daphnine was confirmed by an X-ray analysis of the dihydroiodide. It was postulated that daphnine, the only bisbenzyliso-quinoline alkaloid with a 7-7 ether linkage, arises by rearrangement of (-)-nortenuipine (114) or its enantiomer, which also occur in Daphnandra species (66). [Pg.28]

Dehydrotelobine (123), C35H32N205, was obtained from the bark of Daphnandra apatela Schodde (Monimiaceae). The NMR spectrum shows great similarity to that of telobine (78), but the UV spectrum ( max 336 nm) indicates a more conjugated system. The alkaloid also has only a weak MS m/e 335 (corresponding to cleavage at a, a major fragmentation mode in reduced alkaloids such as... [Pg.30]

The base jV-methylnorapateline (219), from Daphnandra johnsonii (Monimia-ceae), formed fine white needles of the CHCI3 diadduct, mp 257-259°C (dec.), [a]/,9 +235°, HRMS 548.2307 (C34H32N205). It showed the usual color reaction with H2S04-HN03, the expected UV base shift, and no NMR methoxy resonances. Treatment with CH2N2 gave A-methyltelobine (204), an alkaloid derivative (772) of known structure (103). [Pg.57]

The unusual yellow alkaloid pseudorepanduline (272), C37H38N206, HRMS 606.2723, which occurs in an unclassified Daphnandra species and also in D. dielsii, has mp 168-173°C (dec.), [a] 8 +229° (CHC13), and similar chro-... [Pg.72]
