    Asymmetric synthesis of a key synthetic precursor for(+)-strigol and sorgolactone
    摘要:
    En-route to non-racemic iodomethyl butyrolactone 23g a number of stereoselective 1,4-additions and reductions have been studied. The only satisfactory approach involved baker's yeast reduction (21c-->23c) as key step.

  • Enzymatic Synthesis of Optically Active Lactones<i>via</i>Asymmetric Bioreduction using Ene-Reductases from the Old Yellow Enzyme Family
    作者:Nikolaus G. Turrini、Mélanie Hall、Kurt Faber
    DOI:10.1002/adsc.201500094
    日期:2015.5.26
    activities and stereoselectivities and lactone products were obtained in moderate to excellent yields; importantly, enzyme‐based stereocontrol allowed access to both enantiomers in up to >99% ee. Chiral recognition of a distant γ‐center led to kinetic resolution with remarkable enantioselectivities (E values up to 49). An unprecedented case of dynamic kinetic resolution was observed with 3‐methyl‐5‐phenylfuran‐2(5H)‐one
    与广泛研究的烯还原酶催化的α,β-不饱和羧酸酯的不对称生物还原相反,应用于内酯的反应仍未开发。发现大量烯还原酶可还原各种α,β和γ取代的α,β不饱和丁内酯,以产生相应的饱和非外消旋内酯。取代方式极大地影响了活性和立体选择性,并且以中等至极好的收率获得了内酯产物。重要的是,基于酶的立体控制使两种对映体的ee最高可达99%以上。手性识别远处的γ中心导致动力学拆分,并具有出色的对映选择性(E值高达49)。使用3-甲基-5-苯基呋喃-2(5H)-1,由此底物的自发消旋作用使产物的转化率高达73%,ee大于99%,de高达96%。
