fermentations of S. cinnamonensis, several new 3H-labelled products could be detected. Two products were isolated from bioconversion of (E)-nerolidol, the amide 8 and the 9 (Scheme 2), whereas four products were isolated from the bioconversion of (Z)-nerolidol, the epoxydiol 10, triols 11 and 12, and the tetrahydrofuryl alcohol 13 (Scheme 4). Products 9–13 were obtained as a 1 : 1 mixture of diastereoisomers
产生莫能菌素的生物链霉菌肉桂链霉菌将nerolidol(= 3,7,1 1-trimethyldodeca-1,6,10-trien-3-ol)的(E)和(Z)异构体生物转化为新能力的能力对含氧产品进行了调查。当将每个倍半萜烯的3 H标记外消旋形式添加到肉桂链霉菌的发酵中时,可以检测到几种新的3 H标记产物。从(E)-nerolidol的生物转化中分离出两种产物,酰胺8和9(方案2),从(Z)的生物转化中分离出四种产物。)-橙花醇,环氧二醇10,三醇11和12和四氢呋喃醇13(方案4)。产品9 - 13得到的1:对映异构体的1:1混合物,和12显示出由整体向出现抗除了两个OH基团与三取代(Ž)-double(的键Ž)-nerolidol。橙花醇和乙炔7的两种异构体都是肉桂摇摇培养中莫能菌素产生的抑制剂。
