1H and 13C NMR structure determination of a new stereoisomer of isoreserpiline pseudoindoxyl from Rauvolfia grandiflora |
|
| Abstract: | An NMR study of a new stereoisomer of isoreserpiline pseudoindoxyl alkaloid is described. The complete 1H and 13C NMR assignments of the compound were carried out using COSY, HMQC and HMBC. Stereochemistry at carbons C‐2, C‐3, C‐15, C‐20 and C‐19 was established using values of 1H chemical shifts, coupling constants and NOESY experiments. Copyright © 2003 John Wiley & Sons, Ltd. |
