Stereoselective total synthesis of anti-fungal cyclopentenone (-)-hygrophorone A and cyclopentanone 4-epi-2,3-dihydrohygrophorone H were achieved in high overall yields from d-ribose. An aqueous KOH mediated diastereoselective formation of β-hydroxy ketone with three contiguous chiral centres served as a key step in this synthesis.
从 D-核糖出发,以高总收率实现了抗真菌环戊烯酮(-)- Hygrophorone A 和环戊酮 4-epi-2,3-二氢 Hygrophorone H 的立体选择性全合成。在该合成中,KOH 介导的水相β-羟基酮的非对映选择性形成是关键步骤,其中具有三个连续手性中心。
