A. Wahl et al., ISOLATION AND STRUCTURE ELUCIDATION OF XYLOBUXIN, A NEW NEOLIGNAN FROM XYLOPIA-BUXIFOLIA, Journal of natural products, 58(5), 1995, pp. 786-789
The structure of a new lignan named xylobuxin, isolated from the stem
bark of Xylopia buxifolia, has been elucidated by spectroscopic method
s, mainly 1D and 2D nmr, and chemical transformations. The relative st
ereochemistry for xylobuxin was deduced by nOe spectroscopy and calcul
ations from models.
