  Core Structure of Eremophilanes and Bakkanes through Niobium Catalyzed Diels−Alder Reaction:  Synthesis of (±)-Bakkenolide A

  摘要：

  A suitable intermediate for the synthesis of eremophilanes and bakkanes was prepared by a highly regioselective and stereoselective one-step synthesis through a niobium catalyzed Diels-Alder reaction. As a demonstration of the versatility of this intermediate, a total synthesis of (+)-bakkenolide A is described.

• Rhodium-Catalyzed Oxidative C–H Allylation of Benzamides with 1,3-Dienes by Allyl-to-Allyl 1,4-Rh(III) Migration
  作者：Stamatis E. Korkis、David J. Burns、Hon Wai Lam

  DOI：10.1021/jacs.6b06884

  日期：2016.9.21

  oxidative C-H allylation of N-acetylbenzamides with 1,3-dienes is described. The presence of allylic hydrogens cis to the less substituted alkene of the 1,3-diene is important for the success of these reactions. With the assistance of reactions using deuterated 1,3-dienes, a proposed mechanism is provided. The key step is postulated to be the first reported examples of allyl-to-allyl 1,4-Rh(III) migration

  diols with RCu(CN)Li· BF3, RCu(CN)MgBr·BF3, or RMgBr·CuI (cat) in THF at −78 °C proceeded in SN2′ fashion and resulted in the formation of alkylated (E)-allylic alcohols with remarkably high diastereoselectivity. This reaction represents an efficient 1, 3-chirality transfer method.

  日期：——

  An asymmetric intermolecular [4 + 2] cycloaddition of 1,3-dienes with dialkyl acetylenedicarboxylates, which was catalyzed by a rhodium(i)-chiral phosphoramidite complex, was developed. This protocol provided a highly enantioselective access to prepare carbonyl substituted cyclohexa-1,4-dienes with up to 96% yield and >99% ee. Notably, a cycloaddition on the 10 g scale gave the product in 92% yield

  开发了由铑（i）-手性亚磷酰胺络合物催化的1，3-二烯与乙炔二羧酸二烷基酯的不对称分子间[4 + 2]环加成反应。该方案为制备羰基取代的环己-1,4-二烯提供了很高的对映选择性，产率高达96％，ee大于99％。值得注意的是，在10 g规模上进行环加成反应可得到92％收率和99％ee的产物，这显示出大规模生产羰基取代的环己-1,4-二烯的潜力。另外，还研究了产物的氧化芳构化和水解。

• New strategy in the synthesis of 3-deoxy-D-manno-2-octulosonic acid (KDO), 2-deoxy-KDO and thioglycoside of KDO
  作者：A. Lubineau、J. Augé、N. Lubin

  DOI：10.1016/s0040-4020(01)81292-8

  日期：1993.5

  way to KDO, we developed a new strategy based on an aqueous hetero Diels-Alder reaction with a water-soluble diene derived from D-glyceraldehyde, followed by a dihydroxylation of the newly created double bond. The stereoselectivities of these reactions were investigated to give rise to 2-deoxy-KDO, which was sulfenylated via the enolate to yield β-thioglycoside, the hydrolysis of which led to KDO.

  为了在合成KDO的过程中利用合成中间体的优势，我们开发了一种新的策略，该策略基于含水杂Diels-Alder反应与衍生自D-甘油醛的水溶性二烯的反应，然后对新创建的双键进行二羟基化。研究了这些反应的立体选择性以产生2-脱氧-KDO，其通过烯醇盐被亚硫基化以产生β-硫代糖苷，其水解导致KDO。
