✦ Synopsis

Enantiocontrolled Synthesis of (11S,12S,13S)-(9Z,15Z)-and (11R,12S,13S)-(9Z,15Z)-11-Hydroxy-12,13-epoxy Octadecadienoic Acids by Means of the Sharpless Asymmetric Epoxidation of the Unsymmetrical Divinylcarbinol.

-The enantioselective synthesis of the title compounds (V) and (VI), self-defensive substances against the rice blast disease, employs the Sharpless asymmetric epoxidation of precursor (III) as key step. Only moderate yields are observed. -(HONDA, T.; OHTA,
