从蓝藻FisCherella Muscicola(Thuret)中鉴定了一个新的具有多不饱和侧链的2-吡咯烷酮。其结构经UV、核磁共振和质谱学确证。天然产物的衍生化和衍生物的立体控制合成允许通过手性气相色谱来确定绝对构型。这种新化合物，鱼腥草素B，显示出杀藻特性。版权所有(C)1996爱思唯尔科学有限公司
A new 2-pyrrolidinone with a polyunsaturated side chain has been identified from the cyanobacterium Fischerella muscicola (Thuret). Its structure was elucidated by UV, NMR and mass spectroscopy. Derivatisation of the natural product and stereocontrolled synthesis of the derivative allowed the determination of the absolute configuration by means of chiral gas chromatography. The new compound, fischerellin B, shows algicidal properties. Copyright (C) 1996 Elsevier Science Ltd
