Fomannosin (A) has been implicated in the phytopathogenic activity of the economically important wood rot fungus Fomes annosus which affects pine stands in the Southeastern United States. The structure of this unusual sesquiterpene was established by spectroscopic methods and by X-ray crystallograph

## Abstract The origin of the carbon skeleton of verrucarin E **(1)** from acetate as precursor is confirmed. Incorporation studies with [1,2β^13^C]βacetate have demonstrated that two acetoacetate units couple together as shown in pattern **A** __(Scheme 2)__ and not as in **B**. Analysis of the de
The fate of acetate hydrogen in polyketide biosynthesis is an interesting subject which has not been studied in detail. 2 H and 3R-RMR spectrometries have been applied to tracing acetate hydrogen in the biosynthesis of griseofulvin 2) and penicillic acid.3) Recently we reported a new method utilizin
