  Charge-directed conjugate addition reactions of silylated .alpha.,.beta.-unsaturated amidate anions

  摘要：

  A variety of N-substituted alpha-silylated-alpha,beta-unsaturated amidate anions (2) have been found to be excellent Michael acceptors in charge-directed conjugate addition reactions with Grignard and organolithium reagents. The effects of olefin substitution, Si-substitution, N-substitution, and amidate counterion have been studied. Anionic acceptors may be prepared in situ by the addition of silylated vinyllithium reagents to isocyanates and then allowed to undergo conjugate addition reactions with subsequently added nucleophiles, but it was found to be more efficient to isolate neutral acceptors and regenerate the acceptor anion through the use of excess nucleophile. Beta-Substituted acceptors were found to react only with reactive organolithium reagents while a beta,beta-disubstituted acceptor failed to undergo conjugate addition reactions. A primary amide acceptor (14d) also undergoes addition reactions with larger quantitites of nucleophiles suggesting that dianionic amidate acceptors (31) are involved. Diene acceptor 24 was found to undergo a 1,6-addition reaction with n-BuLi. Sodium and potassium amidate salts were found to be inferior to lithium and magnesium salts in addition reactions in keeping with the expectation that an increase in carbonyl-group charge burden retards conjugate reactions. Triphenylsilyl-containing acceptor 16 was found to be more reactive in reactions with n-BuMgCl but less reactive with bulkier tert-BuMgCl. Adduct dianions can be monoalkylated with alkyl iodides and used in Peterson olefination reactions.

  镍催化未活化烯烃的抗马尔科夫尼科夫氢二氟烷基化反应

  摘要：

  通过使用PhSiH 3作为氢化物源，开发了一种有效的Ni 催化的未活化烯烃与溴二氟乙酸盐的氢二氟烷基化反应。该转化提供了具有抗马尔科夫尼科夫区域选择性的脂肪族二氟化物。广泛的高度远程烯烃、简单烯烃、药物分子、市售CF 2前体，甚至非氟化底物在温和条件下都能胜任该反应，证明了该策略的实用性。此外，机理研究表明，二氟烷基自由基可能是这种转变的关键中间体。

  commodity feedstock: ethyl trifluoroacetate. A novel mechanistic approach was identified using our previously developed diaryl ketone HAT catalyst to enable the hydroalkylation of a diverse suite of alkenes. Furthermore, electrochemical studies revealed that more challenging radical precursors, namely trifluoroacetamides, could also be functionalized via synergistic Lewis acid/photochemical activation

  尽管宝石-二氟亚甲基具有诱人的结构、物理和生化特性，但将其安装到有机结构中仍然是一项艰巨的合成挑战。一种非常有效的逆合成方法是将来自三氟甲基的单个 C-F 键功能化。这一系列攻击的最新进展使三氟甲基芳烃的 C-F 活化成为可能，但将可访问的基序限制为仅苄基宝石-二氟化支架。相比之下，三氟乙酸盐的 C-F 活化将使它们能够用作双功能宝石-二氟亚甲基合成子。在此，我们报告了一种光化学介导的商品原料脱氟烷基化方法：三氟乙酸乙酯。使用我们之前开发的二芳基酮 HAT 催化剂确定了一种新的机制方法，以实现多种烯烃的加氢烷基化。此外，电化学研究表明，更具挑战性的自由基前体，即三氟乙酰胺，也可以通过协同路易斯酸/光化学活化进行功能化。最后，该方法为 FDA 批准的药物化合物的新型宝石-二氟类似物提供了一种简洁的合成方法。

  palladium‐catalyzed intermolecular arylcarbonylation of unactivated alkenes has been developed. Unsymmetrical diaryliodonium salts (DAISs) were used as arylation reagents, the bulky aryl group (ArL) of which was exclusively incorporated into the arylcarbonylated products, which contained the ArL group and a carboxylic ester group at the α‐ and β‐carbon position, respectively, of the original terminal C−C

  dipolarophile and the münchnone on the intramolecular cycloaddition outcome was examined. It was found that either nonactivated or electron-poor alkenes can react with the münchnone if these alkenes are tethered at position 4 on the münchnone (2, R2 = alkene tether), whereas only an electron-poor alkene at position 2 (2, R3 = alkene tether) could undergo successful cycloaddition. Also, münchnones substituted

  N-酰基氨基酸的化学选择性活化，慕尼黑酮生成，分子内1,3-偶极环加成和开环的序列有效地产生了官能化的多环结构，例如环戊[ b ]吡咯或两性离子双环[4.3.0]壬烷或双环[3.3]。 [0]在一个操作中给出了辛烷值。这些两性离子物质是首次分离，然后还原为双环氨基醇。考察了双极亲和物和慕尼黑酮的取代对分子内环加成反应的影响。发现如果未活化的或贫电子的烯烃都可以在慕尼黑（4，R 2=烯烃系链），而只有位置2（2，R 3 =烯烃系链）的电子贫烯可成功进行环加成。同样，在位置2处被苯基（2，R 3 = Ph）取代的慕尼黑橡胶显示出显着的反应活性，而在位置4（2，R 2 = Ph）处的苯基具有非常有限的作用。

  An alternate synthetic route to the important anticancer drug suberoylanilide hydroxamic acid (SAHA) from its α,ß-didehydro derivative is described. The didehydro derivative is obtained through a cross metathesis reaction between a suitable terminal alkene and N-benzyloxyacrylamide. Some of the didehydro derivatives of SAHA were preliminarily evaluated for anticancer activity towards HeLa cells. The
