Abstract
AbstractStereochemical assignments of yuanhuacin were performed through two‐dimensional COSY, ROESY, 1H and 13C shift correlation spectroscopy (HETCOR and FLOCK), and ambiguous assignments were resolved through molecular modeling comparisons. This combination of techniques is applicable for the assignment of 1H and 13C chemical shifts of polycyclic compounds containing high percentages of quaternary carbons.
