In this study, we present the first total syntheses of koshidacins A and B, antiplasmodial
cyclic tetrapeptides from fungus, by assembling the side chain in late stage through
olefin cross-metathesis. Additionally, the two diastereoisomers 8,9-epi-koshidacin A and 9-epi-koshidacin B were also synthesized by our synthetic route.
Key words
koshidacin A - koshidacin B - total synthesis - cross-metathesis - antiplasmodial
- cyclic tetrapeptides
