Warifteine and methylwarifteine: 1H and 13C assignments by two‐dimensional NMR spectroscopy |
|
| Abstract: | The identity and structures of warifteine and methylwarifteine, two tertiary bisbenzylisoquinoline alkaloids of an unusual type, were elucidated and verified by 2D NMR spectroscopy. Complete 1H and 13C NMR spectral assignments were obtained. Copyright © 2003 John Wiley & Sons, Ltd. |
