Both reserpine and ajmaline possess chemical structures composed of a tryptamine and a corynanthe unit (Seaion 2.9).Although the complete Cjo unit of the corynanthe system is incorporated in reserpine, in the case of ajmahne one of the carbons is lost. [Pg.77]

The spectroscopic data for a new alkaloid 8 (6) showed a similarity to those reported for anhydrovobasinediol (taberpsychine) (10) 11,12), but a significant NOE observed between H-19 and H-15 in the H-NMR spectrum of 8 suggested that the configuration of the ethylidene side chain was in the Z form. The C-NMR signal due to C-15 of 8 was observed downfield (7.0 ppm) and, in contrast, that of C-21 was observed upheld (6.9 ppm) compared to the corresponding signal of 10. The structure of 8 inferred by spectroscopic analysis to be 19(Z)-anhydrovobasinediol was confirmed by chemical synthesis from ajmaline (Section II.B). [Pg.5]
