  Nickel(0)-Mediated Sequential Addition of Carbon Dioxide and Aryl Aldehydes into Terminal Allenes

  摘要：

  [GRAPHICS]Nickel-mediated sequential addition of carbon dioxide and aryl aldehydes into terminal allenes; is reported. The reaction proceeded in a diastereoselective manner to afford alpha-methylene-gamma-hydroxy carboxylic acids, which allowed stereoselective preparation of cis-beta,gamma-disubstituted alpha-methylene-gamma-lactones.

  Studies on Pd(II)-Catalyzed Coupling−Cyclization of α- or β-Amino Allenes with Allylic Halides

  摘要：

  The palladium-catalyzed coupling-cyclization of alpha- or beta-amino allenes with allylic halides leading to 3-allylic 2,5-dihydropyrroles and 1,2,3,6-tetrahydropyridines, respectively, was studied. The starting materials are easily available. The skeletons of both two classes of products were established by the X-ray diffraction studies of 7i and 9b. Through the study of the reaction of 2b with 3-chloro-1-butene, 1-chloro-2-butene, and pi-allyl palladium species and the stereochemical outcome of the coupling cyclization of (S)-2m and (R)-2n, it is believed that the current transformation most likely proceeded via a Pd(II)-catalyzed pathway, although a Pd(0) pathway cannot be completely excluded.

  We have realized a cyclization reaction of 2,3-allenoic acids 1 in the presence of simple alkyl- or aryl-substituted allenes 3. In this reaction, the cyclic oxypalladation of 2,3-allenoic acid with Pd(II) would afford the furanonyl palladium intermediate 2, which could be trapped by the simple allene to afford a pi-allylic intermediate anti-9. This intermediate anti-9 could be nucleophilically attacked

  我们已经在简单的烷基或芳基取代的丙二烯 3 存在下实现了 2,3-丙烯酸 1 的环化反应。在该反应中，2,3-丙烯酸与 Pd(II) 的环氧基钯化反应将得到呋喃基钯中间体 2，它可以被简单的丙二烯捕获，得到 pi-烯丙基中间体 anti-9。这种中间体 anti-9 可以被 Br- 亲核攻击以产生 4-(1'-bromoalk-2'(Z)-en-2'-yl)furan-2(5H)-one 衍生物 Z-5 和 Pd( 0）。苯醌在 HOAc 中有效地将原位形成的 Pd(0) 转化为具有催化活性的 Pd(II) 物质。在当前条件下，丙二酸、乙酰氧基和邻苯二甲酰胺中的丙二酸、邻苯二甲酰胺等官能团是可以接受的。当使用光学活性的 2,3-丙二烯酸时，观察到手性转移的高效率，这表明中间体 2 的形成是一个高度立体选择性的抗氧化钯化过程。Z-异构体的高度选择性形成可以通过丙二烯3与中间体2中的钯原子的面

  visible-light-driven radical hydrosilylation of allene has been achieved by using eosin Y as the photocatalyst, with thiol and base as additives. Depending on allenes, two types of adducts with E-selectivity were obtained. It was demonstrated that monosubstituted nonarylated allenes reacted to give linear E-allylsilanes, while 1,3-disubstituted electron-deficient allenes afforded E-alkenylsilanes. A radical mechanism
