bromohydrins (–)-(9) and (+)-(9). The bromohydrin (–)-(9) was converted into prostaglandin E2(1) and prostaglandin F2α(2) by reaction of the chiral cuprate reagent (15) with the tricyclic ketone (10), while the bromohydrin (+)-(9) was converted into the prostaglandins by reaction of the epoxyacetal (11) with the same cuprate reagent (15).
使用积极发酵的酵母将外消旋酮(6)转化为非对映异构醇(7)和(8)。将这些醇分离并转化为
溴代醇(-)-(9)和(+)-(9)。通过手性
铜酸盐试剂(15)与
三环酮(10)反应,将
溴代醇(-)-(9)转化为
前列腺素E 2(1)和
前列腺素F2α(2),而
溴代醇(+)- (9)通过环氧
乙缩醛(11)与相同的
铜酸盐试剂(15)反应而转化为
前列腺素。
