Chemistry of Natural Compounds,1974,10(4): 496-503. | Absolute configuration of vinerine and vineridine[Reference: WebLink] |
METHODS AND RESULTS:
On the basis of an analysis of the circular dichroism and NMR spectra the absolute configuration 7R, 3R, 4S, 15S, 19S, 20S has been established for vinerine; 7S, 3R, 4S, 15S, 19S, 20S for Vineridine; and 7S, 3S, 4R, 15S, 19S, 20S for N-acetylvinerine. | Khimiya Prirodnykh Soedinenii,1966,2(4): 260–265. | The structure of vinerine and vineridine[Reference: WebLink] | METHODS AND RESULTS:
1. The epigeal part ofV. erecta gathered in the Tashkent Oblast in the early vegetation period contains a mixture of alkaloids (2.7%). Separation of the total alkaloids gave vincanine, vincanidine, vinervine, akuammine, kopsinine, pseudokopsinine, and the new bases vinerine and Vineridine. 2. The structure of vinerine has been established by a study of the IR, NMR, and mass spectra.
CONCLUSIONS:
Vineridine is isomeric with vinerine at C3 and C7. 3. A new base, hydroxyindole reserpinine, has been obtained from reserpinine. |
