The synthesis of key precursor 5 of the macrolide core of rhizoxin D has been achieved by cross metathesis between two olefinic fragments 6 and 7. Both the olefinic fragments are easily synthesized in a diastereoselective manner from the common precursor 1-benzyloxy-2-methylhex-5-ene-3-ol (8).
通过两个烯烃片段 6 和 7 之间的交叉偏析,合成了根瘤霉素 D 大环内酯核心的关键前体 5。这两种烯烃片段都能以非对映选择性的方式从共同前体 1-苄氧基-2-甲基己-5-烯-3-醇(8)轻松合成。
