Incorporationstudies with 14C-labelled acetates and malonate confirm the polyketide origin of aspyrone (1), and identify the chain starter unit. Five carbons are derived from the methyl group of acetate, and the remaining four from the carboxy group. The pattern of incorporation of tritium from [2-3H]acetate is inconsistent with a biosynthesis from aromatic precursors of the mellein type. Possibly
