Abstract Six new compounds have been identified in the volatile fractions produced during the submerged cultivation of Streptomyces avermitilis . By recording the GC/MS, GC/FTIR, CD, 1 H and 13 C NMR data and by performing chemical degradation experiments, these compounds were determined to be (5 S , S )‐5‐methyl‐3‐(methylalkyl)furan‐2(5 H )‐ones. Herein, the existence of volatile lactones with an anteiso structure of the side‐chain is thus documented for the first time. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
