  钯催化的未活化烯烃与脂肪族伯胺的氧化胺化反应

  摘要：

  未活化的烯烃与伯烷基胺的直接偶联被认为是构建复杂胺的有效但未知的方法。在此，我们报道了基于钯催化剂、双齿膦配体和二氢醌的组合，未活化烯烃与脂肪族伯胺的催化分子间氧化胺化。以良好的收率获得了一系列仲烯丙胺，具有出色的区域选择性和立体选择性。机械控制实验表明，反应通过烯丙基 C(sp 3 )–H 活化和亲核胺化进行。通过药物分子的后期修改和简化合成，进一步证明了该协议的实用性。

  A new lead compound for abscisic acid biosynthesis inhibitors targeting 9-cis-epoxycarotenoid dioxygenase

  摘要：

  9-cis-Epoxycarotenoid dioxygenase (NCED), a key enzyme in abscisic acid (ABA) biosynthesis, cleaves the olefinic double bond of 9-cis-epoxycarotenoid. Several analogues of nordihydroguaiaretic acid (NDGA) were designed and synthesized, and their efficacy as inhibitors of NCED was examined. One of the synthesized compounds (20) was found to be an inhibitor of this enzyme, and inhibited ABA accumulation and stomatal closing, suggesting that 20 should be ABA biosynthesis inhibitor.

• Sulfoxide ligand metal catalyzed oxidation of olefins

  The enantioselective synthesis of isochroman motifs has been accomplished via Pd(II)-catalyzed allylic C—H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide-oxazoline (ArSOX) ligand. The allylic C—H oxidation reaction proceeds with the broadest scope and highest levels asymmetric induction reported to date (avg. 92% ee, 13 examples ≥90% ee). Additionally, C(sp3)-N fragment coupling reaction between abundant terminal olefins and N-triflyl protected aliphatic and aromatic amines via Pd(II)/sulfoxide (SOX) catalyzed intermolecular allylic C—H amination is disclosed. A range of 52 allylic amines are furnished in good yields (avg. 76%) and excellent regio- and stereoselectivity (avg. >20:1 linear:branched, >20:1 E:Z). For the first time, a variety of singly activated aromatic and aliphatic nitrogen nucleophiles, including ones with stereochemical elements, can be used in fragment coupling stiochiometries for intermolecular C—H amination reactions.

  通过Pd(II)-催化的烯烃末端前体的烯丙基C—H氧化，已经实现了对异色烷基苯并环的对映选择性合成。这一目标的成功关键在于开发和利用一种新型手性芳基亚砜-噁唑啉（ArSOX）配体。烯丙基C—H氧化反应具有迄今报道的最广泛范围和最高水平的不对称诱导（平均92% ee，13个例子≥90% ee）。此外，通过Pd(II)/亚砜（SOX）催化的分子间烯丙基C—H胺化揭示了丰富的末端烯烃和N-三氟甲磺酰保护的脂肪族和芳香族胺之间的C(sp3)-N片段偶联反应。一系列52种烯丙基胺以良好的产率（平均76%）和优异的区域和立体选择性（平均>20:1线性:支链，>20:1 E:Z）提供。首次，各种单独活化的芳香族和脂肪族氮亲核试剂，包括具有立体化学元素的试剂，可以在分子间C—H胺化反应的片段偶联化学计量中使用。

  The palladium-catalyzed, substrate-directable Heck-Matsuda reaction of allylamine derivatives with arenediazonium salts is reported. The reaction proceeds under mild conditions, with excellent regio- and stereochemical control as a function of coordinating groups present in the allylamine substrate. The distance between the olefin moiety and the carbonylic system seems to play a key role regarding the regiocontrol. The method presents itself as robust, as simple to carry out, and with wide synthetic scope concerning the allylic substrates and the type of arenediazonium employed. The synthetic potential of the method is illustrated by the short total syntheses of the bioactive compounds naftifine, abamine, and abamine SG.
