  Aldehyde Addition and Copper-Mediated Allylation of Bicyclic Alkoxytitanacyclopentenes and -Pentadienes:  New Selectivities and an Unusual Reaction

  摘要：

  Bicyclic titanacyclopentenes generated in situ from 1,6-enynes and (eta(2)-propene)Ti(O-i-Pr)(2) (1) reacted with aldehydes at their alkenyl-titanium bond in the absence or presence of Ti(O-i-Pr)(n)Cl(4-n) (n = 2 or 3) to give allyl alcohols such as 5-7 as a nearly single stereoisomer in good yields. Upon workup with DCl/D(2)O or iodine, deuterio and iodo derivatives, 8 and 9, were obtained. Bicyclic titanacyclopentadienes prepared analogously from 1,6- or 1,7-diynes and 1 also reacted with aldehydes in the presence of an additional equivalent of Ti(O-i-Pr)(2)Cl(2) to afford 1,2-dialkylidenecyclopentanes pr -cyclohexanes having an alcohol moiety in their side chain in good yields. In place of the simple hydrolysis, deuteriolysis or iodinolysis gave the corresponding derivatives such as 21 or 22. Treatment of 1,6-enyne 10 with 1 in the standard way and then with a slight excess of i-PrMgCl at -50 degrees C generated a new titanium species that, upon reaction with aldehydes, afforded unexpected adducts 34 and 41-45 virtually as a single isomer. Copper-mediated allylation of dialkoxytitanacyclopentene such as 3 with allyl bromide proceeded at their vinyl-titanium bond to give 48 and 50. Likewise, dialkoxytitanacyclopentadiene prepared from 29 and 1 underwent the regioselective copper-mediated mono-allylation to give a 9:1 mixture of 53 and 54. Upon workup with deuteriochloric acid, the corresponding deuterated product was obtained with a high degree of deuterium incorporation.

• Gold(III)-Catalyzed Intramolecular Furanylation and Cyclopropanation of Acyclic Conjugated Enynones
  作者：Chang Oh、Lanhua Piao、Ji Kim

  DOI：10.1055/s-0032-1317926

  日期：——

  furanylation–cyclopropanation of acyclic (E)-deca-2,9-dien-4-yn-1-ones and an (E)-undeca-2,10-dien-4-yn-1-one to give 1-(2-furyl)bicyclo[3.1.0]hexanes and a 1-(2-furyl)bicyclo[4.1.0]heptane, respectively. This requires a configurational change from the E-isomer to the Z-isomer prior to furan formation. The intermediate was proposed to be a gold–carbene, which would undergo cyclopropanation to furnish the product.

• Cobalt Carbonyl-Mediated Carbocyclizations of Enynes:  Generation of Bicyclooctanones or Monocyclic Alkenes

  Depending on the thermolytic conditions, dicobalthexacarbonyl-complexed enynes underwent cyclizations to provide different carbocyclic frameworks. Bicyclopentanones were formed from enyne-Co2(CO)6 complexes, or from enynes that were treated with Co2(CO)8, or more effectively, with Co4(CO)12 in an alcoholic solvent under a H2 or N2 atmosphere. This transformation proceeded via a sequential cyclocarbonylation

  取决于热解条件，二钴六羰基复合的烯炔进行环化以提供不同的碳环骨架。双环戊酮是由烯炔-Co2（CO）6配合物形成的，或者由在乙醇溶剂中在H2或N2气氛下用Co2（CO）8或更有效地用Co4（CO）12处理的烯炔形成。该转化通过顺序的环羰基化和1，4-还原进行，并且是使用羰基钴簇的第一个解释。在这些条件下，大概生成了氢化钴，其介导了烯酮还原为饱和酮。相反，在双氢戊烯酮产物之外，在氢气气氛下在甲苯中二巴杂六羰基络合物的炔炔的热解导致它们的还原环化以中等收率形成单环烯烃。在某些情况下，向反应中加入氢硅烷会完全抑制双环戊烯酮的形成。前者的结果证明了在环加成反应之后发生的反应，而后者描述了在Pauson-Khand反应途径中正常途径中断的另一个例子。

  hydrolysis, deuteriolysis, or iodinolysis, gave diene 8, or its bis-deuterated (>99% d2) and bis-iodinated counterparts (9 and 10), in good yields and with high selectivities. This reaction is applicable to the cross-coupling reaction of functionalized acetylenes such as 2-alkynoates and 2-alkynamides 12−18 and a variety of terminal acetylenes 24−28 to give dienes 36−50 in good yields. A terminal acetylene

• Pauson–Khand reactions in water
  作者：Marie E Krafft、James A Wright、Llorente VR Boñaga

  DOI：10.1139/v05-112

  日期：2005.6.1

  We have investigated the cobalt mediated Pauson–Khand (PK) reaction in water. In the presence of detergents and surfactants, Co₂(CO)₈ and Co₄(CO)₁₂ are effective under aqueous-phase, thermal PK reactions. In a water–Triton^®X-100 medium, Co₄(CO)₁₂ is catalytically active. Further, dicobalthexacarbonyl complexes of alkynes and enynes undergo effective cyclization under thermal (70 °C) and NMO-promoted conditions. The oxidative nature of the latter conditions inhibits the reductive PK reaction. In all protocols, moderate to excellent yields of the cycloadducts are obtained. Substrates that are prone to hydrolysis, such as acetals, highly activated carboxylic acid derivatives, and those bearing propargylic heteroatom groups are tolerated under appropriate conditions. Finally, the more challenging intermolecular cycloadditions can also be easily achieved under aqueous conditions.Key words: alkyne, cycloaddition, green chemistry, Pauson–Khand reaction, water.

  我们已经在水中研究了钴介导的Pauson-Khand（PK）反应。在存在洗涤剂和表面活性剂的情况下，Co₂(CO)₈和Co₄(CO)₁₂在水相、热力PK反应中是有效的。在水-Triton® X-100介质中，Co₄(CO)₁₂具有催化活性。此外，炔烃和烯炔烃的二钴六羰基络合物在热（70°C）和NMO促进条件下进行有效的环化反应。后一条件的氧化性质抑制了还原性PK反应。在所有方案中，环加成产物的产率从中等到优良。易水解的底物，如缩醛、高度活化的羧酸衍生物以及带有丙炔基杂原子基团的底物在适当条件下是可容忍的。最后，更具挑战性的分子间环加成也可以在水相条件下轻松实现。关键词：炔烃，环加成，绿色化学，Pauson-Khand反应，水。
