  恩格尔哈二酮的全合成和结构修正

  摘要：

  报道了大环天然产物恩格尔哈二酮的全合成。这一努力导致已发表的 engelhardione 结构被修改为 pterocarine 的结构。修订反映了一个苯醚环的取代模式从间位到对位的变化。为了证实，随后合成了紫檀香碱 ( 2 ) 及其紧密区域异构体3以进行比较。此外，为了就我们所知，我们的合成1表示具有一个14元的大环二芳基庚的第一个例子的元-元在二苯基醚基团取代模式。

  versatile method for the total synthesis of cyclic diphenyl ether-type diarylheptanoids, acerogenin C, acerogenin L, (±)-galeon, and (±)-pterocarine was described. The Ullmann reaction of suitably substituted linear diphenylheptanoids was employed for the intramolecular formation of the key ether intermediates as the final step. The prerequisite diarylheptanoids were prepared by a series of cross-aldol

  The natural product engelhardione is an underexplored chemotype for developing novel treatments for bacterial infections; we therefore explored this natural product scaffold for chemical diversification and structure–activity relationship studies. Macrocyclic engelhardione and structural regioisomers were synthesized using a series of aldol condensations and selective hydrogenations to generate the 1,7-diarylheptan-3-one derivatives, followed by microwave-assisted intramolecular Ullmann coupling to afford a series of macrocyclic diaryl ether analogs. An extended macrocyclic chemical library was then produced by oxime formation, reductive amination and O-alkylation. Antibacterial evaluation revealed that the reductive amination derivatives 7b and 7d showed moderate activities (minimum inhibitory concentrations: 12.5–25 μg ml−1) against Mycobacterium tuberculosis and Gram-positive pathogens, as well as anti-Gram-negative activity against an efflux impaired Escherichia coli strain. These results provide validated leads for further optimization and development.

  天然产物恩格尔哈酮是一种尚未充分开发的化学类型，可用于开发细菌感染的新疗法；因此，我们探索了这种天然产物的化学多样性，并对其结构-活性关系进行了研究。通过一系列醛缩合和选择性氢化反应，我们合成了大环恩格尔哈酮和结构区域异构体，生成1,7-二芳基庚烷-3-酮衍生物，然后通过微波辅助分子内乌尔曼偶联反应，得到一系列大环二芳基醚类似物。通过肟形成、还原胺化和O-烷基化反应，我们构建了一个扩展的大环化学库。抗菌评估显示，还原胺化衍生物7b和7d对结核分枝杆菌和革兰氏阳性病原体具有中等活性（最低抑菌浓度：12.5-25µg·ml-1），对一种外排受损的大肠杆菌菌株具有抗革兰氏阴性活性。这些结果为进一步优化和开发提供了有效的线索。

  of diarylether heptanoids (DAEHs) with planar chirality due to the strictly constrained conformations in their molecular skeletons. The characterized oxa[1,7]metapara-cyclophane motifs in DAEHs impose great challenges for their enantioselective synthesis. The asymmetric syntheses of (−)-pterocarine and (−)-galeon are demonstrated by employing a chiral phase transfer-catalyzed highly enantioselective

  由于其分子骨架中的构象受到严格限制，因此，萜烯和异戊二烯是具有平面手性的二芳基醚类庚烷（DAEH）的典型实例。DAEHs中特征性的oxa [1,7]甲基对苯二环基序对他们的对映选择性合成提出了巨大挑战。通过使用手性相转移催化的高对映选择性S N Ar环化反应作为形成二芳基醚环烷骨架的关键步骤，证明了（-）-蝶呤和（-）-galeon的不对称合成。

  The syntheses of myricatomentogenin, jugcathanin, galeon, pterocarine, and acerogenin L are reported. Synthetic material was used to measure their optical activities and free energy of activation for racemization. The natural enantiomers of myricatomentogenin, jugcathanin, galeon, and pterocarine were determined to have the same pR absolute stereochemistry. Acerogenins L and C are achlral compounds.

  The first enantioselective Ullmann cross-coupling reactions to prepare diaryl ethers are reported. The reactions were used to prepare the diarylether heptanoid natural products (-)-myricatomentogenin, (-)-jugcathanin, (+)-galeon, and (+)-pterocarine.
