摘要:

The postulated mechanistic pathway from methyl 9β-hydroxy-11-oxo-(-)-kauran-19-oate (1) to a new skeletal ring B aromatic diterpene (2) by rearrangement with boron trifluoride-etherate in acetic anhydride has been proved by means of the13C n.m.r. spectroscopy in combination with deuterium labeling techniques.
