Volatiles emitted by the soil fungi Trichoderma viride 272 and Trichoderma asperellum 328 were collected by using the closed loop stripping analysis (CLSA) headspace technique, and the obtained extracts were analysed by GC/MS. Several alkyl- and alkenyl-2H-pyran-2-ones, including known compounds 6-pentyl-2H-pyran-2-one and (E)-6-(pent-1-en-1-yl)-2H-pyran-2-one, and the new derivatives (E)-6-(pent-
土壤真菌绿色木霉 272 和木霉 328 释放的挥发物通过使用闭环汽提分析 (CLSA) 顶空技术收集,并通过 GC/MS 分析获得的提取物。几种烷基-和链烯基-2H-吡喃-2-酮,包括已知化合物 6-pentyl-2H-pyran-2-one 和 (E)-6-(pent-1-en-1-yl)-2H-pyran -2-one,以及新的衍生物 (E)-6-(pent-2-en-1-yl)-2H-pyran-2-one、6-丙基-2H-pyran-2-one 和 6-发现了庚基-2H-吡喃-2-one。还检测到烯基衍生物 (E)-6-(hept-1-en-1-yl)-2H-pyran-2-one,之前通过 MS 分析从海洋贵腐菌中初步鉴定出来。所有链烯基吡喃酮均通过使用报道的 Stille 偶联合成,然后进行内酯化,而烷基化吡喃酮是通过报道的合成方法通过 5-烷基戊-2-烯-5-内酯的自由基溴
