The enantioselective synthesis of trans-(+)-laurediol, (2S,3S,5R)-5-[(1R)-1-hydroxy-9-decenyl]-2-pentyltetrahydro-3-furanol, and (2S,3S,5S)-5-[(1S)-1-hydroxy-9-decenyl]-2-pentyltetrahydro-3-furanol are described. In addition, a formal synthesis of trans-(-)-kumausyne is also developed. All the synthetic procedures have in common the use of enantiomerically enriched beta-hydroxy-gamma-lactones, easily
反式-(+)-月桂二醇、(2S,3S,5R)-5-[(1R)-1-羟基-9-癸烯基]-2-戊基四氢-3-呋喃醇和(2S,3S,描述了5S)-5-[(1S)-1-羟基-9-癸烯基]-2-戊基四氢-3-呋喃醇。此外,还开发了反式-(-)-kumausyne 的正式合成方法。所有合成程序的共同点是使用对映体富集的 β-羟基-γ-内酯,可通过 Sharpless 不对称二羟基化 (AD) 从合适的 β,γ-不饱和酯轻松获得。使用 Katsuki-Sharpless 不对称环氧化 (AE) 作为额外的对映选择性反应可提供高对映体纯度的环状化合物。
