We have designed a convergent path for the synthesis of the key fragments (C1–C7 and C6–C22) of phostriecin. The approach not only provides ready access to several biologically active molecules, such as 5‐hydroxygoniothalamin, 5‐acetoxygoniothalamin, and their analogues, but also (S)‐5‐[(S)‐1‐hydroxyallyl]furan‐2(5H)‐one derivatives with cross metathesis as the key reaction.
The synthesis of phomopsolide B has been achieved using an olefin cross-metathesis (CM) reaction as key step. Two metathesis partners, enediol and 5-hydroxy vinyl lactone were prepared from L-ascorbic acid. This is the first report of using 5-hydroxy vinyl lactone in an olefin cross-metathesis reaction.
