Fusicoccin. Part IV. The structure of fusicoccin J

Abstract

The structure (III) of fusicoccin J, a minor glucoside produced by Fusicoccum amygdali, has been determined by its synthesis from fusicoccin (Ia). Feeding experiments have established that fusicoccin J can act as an efficient precursor of fusicoccin. This suggests that the new fusicoccin is a late intermediate on the biosynthetic pathway.
