  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.

• Allene C(sp²)–H Activation and Alkenylation Catalyzed by Palladium

  The selective transition-metal-mediated activation of C(sp2)–H bonds of allenes is a formidable challenge because of the competitive, intrinsic reactivity of cumulated double bonds. Herein, we report a Pd-catalyzed C–H alkenylation of electronically unbiased allenes, affording penta-1,2,4-triene products in up to 94% yield. A picolinamide directing group enables the formation of putative allenyl-palladacycles

  由于累积双键的竞争性、内在反应性，丙二烯的 C(sp 2 )-H 键的选择性过渡金属介导的活化是一项艰巨的挑战。在此，我们报道了电子无偏丙二烯的 Pd 催化 C-H 烯基化，以高达 94% 的产率提供五-1,2,4-三烯产物。吡啶酰胺导向基团能够形成假定的烯基-钯环，其随后与缺电子烯烃偶联伙伴参与限制周转的 Heck 型反应。这种机制提议与实验和计算研究一致。此外，我们首次报道了使用吡啶酰胺 N , O-缩醛作为 C-H 活化反应的易于去除的助剂，可以有效地进行烯基甲醇衍生物的烯基化。证明了在不影响产物的反应性五-1,2,4-三烯亚结构的情况下成功去除导向基团。

• Ruthenium-Catalyzed Cyclocarbonylation of Allenyl Alcohols and Amines:  Selective Synthesis of Lactones and Lactams
  作者：Eiji Yoneda、Shi-Wei Zhang、Da-Yang Zhou、Kiyotaka Onitsuka、Shigetoshi Takahashi

  Allenyl alcohols such as 4-hydroxybuta-1,2-dienes and 5-hydroxypenta-1,2-dienes having a variety of substituents undergo cyclocarbonylation in the presence of a ruthenium catalyst under mild conditions selectively to give five- and six-membered lactones in a high yield with 100% atom economy. 5-Aminopenta-1,2-dines are also cyclocarbonylated to give gamma-lactams. A possible carbonylation mechanism involving a ruthenium cluster intermediate is proposed on the basis of experimental results.
