  摘要：

  到高度官能化的α，β不饱和δ内酯的柔性对映选择性途径，已经允许用于styryllactones的合成：altholactone，isoaltholactone，3-外延-altholactone，2-外延-altholactone和5-羟基goniothalamin在2.5，10，糠醛的总收率分别为5％，1％和13％。通过将Sharpless催化不对称二羟基化反应应用于乙烯基呋喃，此方法可得出其不对称性。所产生的二醇以高对映体过量产生，并且可以通过短的高度非对映选择性氧化和还原序列立体选择性地转化为α，β-不饱和-δ-内酯。使用维蒂希（Wittig）烯化或朱莉娅（Julia）烯化反应来引入顺式或反式的苯基侧链 选择性地将这些中间体通过选择性环氧化反应进一步精制为内酯异构体。

  Enantioselective Syntheses of Isoaltholactone, 3-epi-Altholactone, and 5-Hydroxygoniothalamin

  摘要：

  GRAPHICSA flexible enantioselective route to highly functionalized alpha,beta-unsaturated delta-lactones has allowed for the syntheses of the styryllactones: isoaltholactone, 3-epi-altholactone, and 5-hydroxygoniothalamin in 10%, 5%, and 13% overall yields from furfural, respectively. This approach derives its asymmetry by applying the Sharpless catalytic asymmetric dihydroxylation to vinylfuran. The resulting diols are produced in high enantioexcess and can be stereoselectively transformed into alpha,beta-unsaturated delta-lactones via a short highly diastereoselective oxidation and reduction sequence.

  A flexible, enantioselective route to highly functionalized α,β-unsaturated δ-lactones has been applied to the synthesis of 7-oxa-phomopsolide E and its C-4 epimer. This approach relies on the application of the Noyori asymmetric hydrogenation of furyl ketone to produce the secondary furyl alcohol in high enantioexcess, which can be stereoselectively transformed into α,β-unsaturated-δ-lactones by a

  由于需要多个步骤以及许多选择性保护和脱保护，寡糖合成受到阻碍。在此，我们报告了一种用于生物和药物结构活性研究的各种寡糖基序的高效从头途径。整体效率的关键是明智地使用不对称催化和合成设计。这些绿色原则包括双向使用高度立体选择性催化（Pd（0）催化的糖基化/后糖基化）。此外，CC 和 CO π 键官能团的化学选择性使用，作为无原子保护基团以及异头导向基团（通过 Pd-π-烯丙基），突出了通往发散路线的原子经济方面一组天然和非天然寡糖（即，低聚糖的各种 d-/l-非对映异构体以及缺乏 C-2 异头导向基团的脱氧糖）。例如，仅用 12 个步骤，就从非手性酰基呋喃构建了具有 35 个立体中心的高度支化七糖。
