The studies which led to the complete structure elucidation of the antibiotic aurodox, including the chiralities of all eleven asymmetric centers and the cis–trans isomerism of all seven exocyclic double bonds, are summarized. Aurodox was correlated stereochemically with mocimycin. Thus, aurodox can be described as N-[7-[5(R)-[7-[1,2-dihydro-4-hydroxy-1-methyl-2-oxo-3-pyridinyl]-6-methyl-7-oxo-1(E),3(E),5(E)-heptatrienyl]tetrahydro-3(S),4(R)-dihydroxyfuran-2(S)-yl]-6(S)-methoxy-5,7(R)-dimethyl-2(E),4(E)-heptadienyl]-α(S)-ethyl-5,5-dimethyltetrahydro-2(R),3(R),4(R)-trihydroxy-6(S)-[1(E),3(Z)-pentadienyl]-2H-pyran-2-acetamide. Mocimycin, probably identical with kirromycin, is the corresponding N-desmethyl homolog.
这些研究导致了抗生素奥罗多克斯的完整结构阐明,包括所有十一个手性中心的手性以及所有七个外环双键的顺式-反式异构体。奥罗多克斯在立体化学上与莫西霉素相关。因此,奥罗多克斯可以描述为N-[7-[5(R)-[7-[1,2-二氢-4-羟基-1-甲基-2-酮-3-吡啶基]-6-甲基-7-酮-1(E),3(E),5(E)-庚三烯基]四氢-3(S),4(R)-二羟基呋喃-2(S)-基]-6(S)-甲氧基-5,7(R)-二甲基-2(E),4(E)-庚二烯基]-α(S)-乙基-5,5-二甲基四氢-2(R),3(R),4(R)-三羟基-6(S)-[1(E),3(Z)-戊二烯基]-2H-吡喃-2-乙酰胺。莫西霉素,可能与基罗霉素相同,是相应的N-去甲基同系物。
