Synthetic routes to geosmin and its enantiomer are well established, but the enantioselective synthesis of stereoisomers of geosmin is unknown. Here a stereoselective synthesis of all stereoisomers of geosmin is reported, yielding all compounds in high enantiomeric purity. Furthermore, the stereoselective synthesis of a geosmin derivative isolated from a mangrove associated streptomycete was performed,
土臭素及其对映体的合成路线已很成熟,但土臭素立体异构体的对映选择性合成尚不清楚。这里报道了土臭素所有立体异构体的立体选择性合成,产生了高对映体纯度的所有化合物。此外,还对从红树林相关链霉菌中分离出的土臭素衍生物进行了立体选择性合成,建立了天然产物的绝对构型。最后,从Streptomyces ambofaciens中分离出土臭素合酶的新副产物,并通过核磁共振波谱阐明了其结构。通过立体选择性合成确定了这种新化合物的绝对构型。
