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, 1H and 13C NMR data and by performing chemical degradation experiments, these compounds were determined to be (5S,S)-5-methyl-3-(methylalkyl)furan-2(5H)-ones. Herein, the existence of volatile lactones with an anteiso structure of
在 Streptomyces avermitilis 水下培养过程中产生的挥发性组分中已鉴定出六种新化合物。通过记录 GC/MS、GC/FTIR、CD、1H 和 13C NMR 数据并进行化学降解实验,这些化合物被确定为 (5S,S)-5-甲基-3-(甲基烷基)呋喃-2( 5H)-一个。在此,首次记录了具有侧链反异结构的挥发性内酯的存在。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
