    Gold-Catalyzed Cyclization of Allene-Substituted Malonate Esters:  Synthesis of β,γ-Unsaturated δ-Lactones
    摘要:
    An efficient method for the preparation of beta,gamma-unsaturated delta-lactones has been developed. The starting materials for the synthesis of these compounds are allene-substituted malonates which undergo gold-catalyzed cyclization by means of nucleophilic attack of the ester moiety on the allene. It is worth mentioning that this is the first example where an ester group attacks as a nucleophile in a gold-catalyzed transformation of allenes.

  • An Unexpectedly Mild Thermal Alder−Ene-Type Cyclization of Enallenes
    作者:Katja Närhi、Johan Franzén、Jan-E. Bäckvall
    DOI:10.1021/jo060013g
    日期:2006.3.31
    A mild, thermal Alder−ene reaction of enallenes has been developed. The allenic double bond acts as the “ene” and generates a carbon−carbon bond to an unactivated olefinic “enophile” in DMF at 120 °C to give [n.3.0] bicyclic systems (n = 3−5) in good yields. Except for a minor [2 + 2] cycloaddition byproduct, the reaction proceeded with complete atom economy, as there is no requirement of a catalyst
    已经开发了温和的烯属烃热的Alder-ene反应。烯丙基双键充当“烯”,并在120°C下与未活化的烯烃“亲烯体”产生碳-碳键,从而以高收率得到[ n .3.0]双环体系(n = 3-5)。除了少量的[2 + 2]环加成副产物外,该反应以完全的原子经济性进行,因为不需要催化剂或其他反应物,并且在此过程中不会形成废产物。
  • Palladium-Catalyzed Oxidative Borylative Carbocyclization of Enallenes
    作者:Andreas K. Å. Persson、Tuo Jiang、Magnus T. Johnson、Jan-E. Bäckvall
    DOI:10.1002/anie.201008032
    日期:2011.6.27
    An efficient oxidative carbocyclization/borylation of enallenes uses Pd(OAc)2 as the catalyst, B2pin2 as the boron‐transfer reagent, and 1,4‐benzoquinone (BQ) as the oxidant (see scheme). The reaction seems to take place through activation of the allene by a PdII complex to give an alkenyl–PdII intermediate followed by carbopalladation of the olefin and subsequent cleavage of the intermediate palladium–carbon
    一种有效的氧化enallenes的carbocyclization /硼基化使用的Pd(OAC)2作为催化剂,B 2销2作为硼转移试剂,和1,4-苯醌(BQ)作为氧化剂(参见方案)。该反应似乎是通过Pd II络合物活化丙二烯生成链烯基-Pd II中间体,然后烯烃进行碳钯催化,随后硼试剂裂解中间的钯-碳键而发生的。
  • Pd-Catalyzed Borylative Cyclization of Allenynes and Enallenes
    作者:Virtudes Pardo-Rodríguez、Juan Marco-Martínez、Elena Buñuel、Diego J. Cárdenas
    DOI:10.1021/ol9017694
    日期:2009.10.15
    Pd-catalyzed cyclization of 1,5- and 1,6-allenynes and 1,5-enallenes with bis(pinacolato)diboron affords synthetically useful allylboronates and alkylboronates under smooth conditions in a formal hydroborylative carbocyclization reaction. One C−C and one C−B bond are formed in a single operation. The reaction outcome implies that different mechanisms operate for the reactions of allenynes and enallenes
    用双(频哪醇)二硼进行Pd催化的1,5-和1,6-炔烃和1,5-烯醛的环化反应,可在顺畅的条件下,在正式的氢硼烷基化碳环化反应中提供合成上有用的烯丙基硼酸酯和烷基硼酸酯。在一次操作中形成一个C-C和一个C-B键。反应结果表明,不同的机理分别作用于丙炔和烯丙烯的反应,实际途径取决于炔烃或烯烃相对于丙二烯部分的相对反应性。所获得的环化硼酸酯可通过与醛的氧化或烯丙基化反应而官能化。
  • Aerobic Oxidations Catalyzed by Zeolite-Encapsulated Cobalt Salophen
    作者:Mikael Johansson、Byron W. Purse、Osamu Terasaki、Jan-E. Bäckvall
    DOI:10.1002/adsc.200800294
    日期:2008.8.4
    salophen catalysts were prepared using the “ship-in-a-bottle technique” where the complex was synthesized in the super cage of the zeolite and therefore locked into the pocket. The encapsulated catalysts were then tested in the aerobic oxidation of hydroquinone to p-benzoquinone; the best encapsulated catalyst was shown to be an efficient electron-transfer mediator in a palladium-catalyzed aerobic oxidative
    钴Salophen被封装在一系列沸石中,这些沸石具有不同的硅铝原子比和不同的阳离子。使用“瓶中装船技术”制备沸石-钴盐基酚催化剂,其中在沸石的超级笼中合成配合物,因此将其锁定在袋中。然后,将包封的催化剂在氢醌到的有氧氧化测试p苯醌; 在钯催化的好氧氧化碳环化反应中,最好的封装催化剂被证明是有效的电子转移介体。
  • Carbon−Carbon Bond Formation in Palladium(II)-Catalyzed Allylic Oxidation:  A Novel Oxidative Carbocyclization of Allene-Substituted Olefins
    作者:Johan Franzén、Jan-E. Bäckvall
    DOI:10.1021/ja029505a
    日期:2003.5.1
    efficient palladium(II)-catalyzed oxidative carbocyclization has been developed. It was found that allene-substituted olefins 1 cyclized in the presence of 1 mol % Pd(O2CCF3)2 and p-benzoquinone (2 equiv) to give bicyclic ring systems 2 in good to excellent yields. The cyclization constitutes a new type of carbon-carbon bond forming reaction between an allene and an olefin under oxidative conditions
    开发了一种新的高效钯(II)催化氧化碳环化。发现丙二烯取代的烯烃1在1mol%Pd(O 2 CCF 3 ) 2 和对苯醌(2当量)存在下环化,以良好至极好的产率得到双环系统2。环化构成了丙二烯和烯烃在氧化条件下形成的新型碳-碳键形成反应。
