  Progress towards the Total Synthesis of Scytonemin A: Asymmetric Synthesis of (2S,3R,4R)-4-hydroxy-3-methylproline

  摘要：

  During the total synthesis of the novel cyclopeptide scytonemin A, the fragment containing two (2S,3R,4R)-4-hydroxy-3-methylproline units was successfully prepared. Two approaches leading to (2S,3R,4R)-4-hydroxy-3-methylproline have been explored. They involve the following key transformations: asymmetric crotylation, Sharpless epoxidation-subsequent epoxide opening, intramolecular amidomercuration-oxidation.
