The complete absolute configuration of hormaomycin 1 a has been established by HPLC and HPLC/MS experiments with appropriately derivatized 4-propylprolines, (2S,4S)-6 and (2R,4R)-6, as well as 4-(Z)-propenylprolines, cis-5 and trans-5, and also feeding experiments with enantiomerically pure samples of the deuterium-labeled 3-(2'-nitrocyclopropyl)alanine, (2S)-3,3-[D2]15 and (2S)-2,2'-[D2]15, and 4
荷马霉素1a的完整绝对构型已通过HPLC和HPLC / MS实验确定,其中含有适当衍生的4-丙基脯氨酸(2S,4S)-6和(2R,4R)-6以及4-(Z)-丙烯脯氨酸,顺式5和反式5,以及用氘标记的3-(2'-硝基环丙基)丙氨酸,(2S)-3,3- [D2] 15和(2S)- 2,2'-[D2] 15和4-(Z)-丙烯基脯氨酸2',4- [D2]-(2S,4R)-5。首次制备了后五个氨基酸,并允许一个人明确地分配了Hormaomycin 1a中最后四个立体中心的迄今未知的绝对构型。另外,还收集了有关该分子生物合成的一些新信息。
