| Outline of Final Research Achievements |
Synthesis of urupocidin A was examined. The left segment of urupocidine A was synthesized stereoselectively starting from 4-octynoic acid via coupling with the acetylide, asymmetric reduction, trans reduction, epoxidation, reduction of the epoxide and oxidation. The lactone intermediate possessing the framework and asymmetric centers of the left segment was obtained. On the other hand, the right segment was synthesized via Keck asymmetric allylation, mesylation and Gabriel syntheses.
