A formal total synthesis of fostriecin has been accomplished
in 20 steps. Our method features the derivation of two of the four
chiral centers from commercial diethyl d-(+)-malate.
The key steps involve the Julia-Kocienski olefination,
the Sharpless asymmetric dihydroxylation, and the Stille coupling.
