  • Synthesis and Stereochemistry of the Four Himachalene-Type Sesquiterpenes Isolated from the Flea Beetle (Aphthona flava) as Pheromone Candidates
    作者:Shin-etsu Muto、Masahiko Bando、Kenji Mori
    DOI:10.1002/ejoc.200300812
    日期:2004.5
    8-tetramethyl-1,2,3,4,5,6,5a-heptahydrobenzo[1,2-a][7]annulene (3), and 1,1,5,8-tetramethyl-1,2,3,4,5-pentahydrobenzo[a][7]annulene (ar-himachalene, 4). The stereochemistry of these himachalene-type sesquiterpenes isolated from flea beetles such as Aphthona flava and Phyllotreta cruciferae as their male-pheromone components was revised to (1S,2R)-1, (6R,7S)-2, (5R,5aS)-3, and (R)-4.

  • Synthesis of (R)-ar-turmerone and its conversion to (R)-ar-himachalene, a pheromone component of the flea beetle: (R)-ar-himachalene is dextrorotatory in hexane, while levorotatory in chloroform
    作者:Kenji Mori

    日期:2005.2
    (R)-ar-Turmerone was synthesized from (4-methylphenyl)acetic acid by employing Evans asymmetric alkylation as the key step. (R)-ar-Turmerone was converted to (R)-ar-himachalene, which was dextrorotatory in hexane while levorotatory in chloroform. Enantiomerically impure (75% ee) (R)-3-(4-methylphenyl)butanoic acid crystallized more readily than the enantiomerically pure one.

  • Stereospecific Hydrogenolysis of Lactones: Application to the Total Syntheses of (<i>R</i>)-<i>ar</i>-Himachalene and (<i>R</i>)-Curcumene
    作者:Kim Spielmann、Renata Marcia de Figueiredo、Jean-Marc Campagne
    DOI:10.1021/acs.joc.7b00419
    日期:2017.5.5
    A straightforward strategy for the syntheses of curcumene and ar-himachalene is reported. Synthetic highlights include a catalytic and asymmetric vinylogous Mukaiyama reaction and a stereospecific hydrogenolysis of a tertiary benzylic center using Pd/C or Ni/Raney catalysts. Notably, using Ni/Raney, the stereoselectivity outcome (inversion vs retention) of the hydrogenolysis depends on the tertiary

    A convenient synthesis of (6 R,7 S)-(+)-himachala-9,11-diene, the pheromone of the chrysomelid beetle Phyllotreta striolata is described. The diene is obtained in a single op eration by a spon- taneous "bromination/dehydrobromination" of 2,6,6,9-tetramethylbicyclo(5.4.0)undec-8-ene. The halogenation/dehalogenation sequence proceeds spontaneously in CCl 4, and is less uniform in CH 2Cl 2 and CHCl 3
    描述了 (6 R,7 S)-(+)-himachala-9,11-diene 的方便合成,这是 chrysomelid 甲虫 Phyllotreta striolata 的信息素。二烯是通过 2,6,6,9-四甲基双环 (5.4.0) 十一碳-8-烯的自发“溴化/脱溴化氢”在单次操作中获得的。卤化/脱卤序列在 CCl 4 中自发进行,在 CH 2Cl 2 和 CHCl 3 中不太均匀。在自由基清除剂二叔丁基-4-甲基苯酚存在下进行的 1 H NMR 实验表明,这是离子机制反应。理论计算表明,自发反应得益于 Br 2 对双键的强烈加成以及起始烯烃和二烯信息素之间几乎中性的能量差异。
  • Enantioselective synthesis of the essential oil and pheromonal component ar-himachalene by a chiral pool and chirality induction approach
    作者:Subhash P. Chavan、Harshali S. Khatod
    DOI:10.1016/j.tetasy.2012.09.008
    日期:2012.10
    The enantioselective synthesis of both isomers of ar-himachalene has been achieved starting from enantiomerically pure citronellal and p-methyl alpha-methyl styrene as an application of a chiral pool and chirality induction approach, respectively. The key reactions involved in the synthesis include the Sharpless asymmetric dihydroxylation for the induction of chirality at benzylic carbon bearing the methyl group and the use of a hypervalent iodine reagent or trimethylsilyldiazomethane (TMSCHN2) for the six to seven membered ring expansion.
