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