  Stereocontrolled rearrangement of silylated vinyloxiranes into α-trialkylsilyl-β,γ-unsaturated aldehydes

  摘要：

  Silylated vinyloxiranes 1, substituted on the double bond, have been synthesized and reacted under very mild conditions in the presence of a catalytic amount of palladium (0). They rearrange into alpha-silylated-beta-gamma-unsaturated aldehydes 2, not only with complete chirality transfer but also with total retention of the double bond stereochemistry.

  We report here an efficient one-pot diastereoselective procedure which transforms silylated vinyloxiranes 2 into enantiomerically pure tetrasubstituted δ-lactones 7, 10. This transformation includes four steps: palladium(0)-catalyzed rearrangement/alkylation-lactonization/1,4-conjugated addition/electrophilic trapping of the intermediary enolate. These reactions allow efficient control of four contiguous

  我们在这里报告其变换甲硅烷基化vinyloxiranes一种高效一锅非对映选择性方法2到对映体纯的四取代的δ内酯7，10。该转化包括四个步骤：中间烯醇化物的钯（0）催化的重排/烷基化-内酯化/ 1,4-共轭加成/亲电捕集。这些反应可以有效地控制四个连续的立体异构中心，当亲电试剂为前手性苯甲醛时，甚至可以控制第五个。

  Rearrangement of silylated vinyloxiranes into highly functionalized α-silylated-β,γ-unsaturated aldehydes occurs with total chirality transfer and retention of double bond configuration under Pd(0) catalysis. We show that this reaction is a versatile tool in the field of total stereoselective synthesis: enantiomerically pure lactones are obtained. The pheromone 6-n-undecyltetrahydro-2-pyrone 2 and massoilactone, 5-hydroxy-2-decenoic acid lactone 3, are synthesized. We describe herein a novel highly diastereoselective route to α,β-unsaturated-γ-silylated-δ-substituted-δ-lactones 1.

  在Pd(0)催化下，硅化的乙烯氧杂环在重新排列过程中转化为高度功能化的α-硅化-β,γ-不饱和醛，同时实现了完全的手性转移及双键构型的保持。我们展示了这一反应作为全立体选择性合成领域的多功能工具：可以获得对映体纯的内酯。合成了信息素6-n-undecyltetrahydro-2-pyrone 2和质量内酯5-hydroxy-2-decenoic acid lactone 3。我们在此描述了一条新颖的高二面体选择性路线，以合成α,β-不饱和-γ-硅化-δ-取代的δ-内酯1。
