  • Stereoselective synthesis of the obscure mealybug pheromone by hydrogenation of a tetrasubstituted alkene precursor
    作者:Yunfan Zou、Jocelyn G. Millar
    DOI:10.1016/j.tetlet.2011.06.030
    日期:2011.8
    An improved diastereoselective synthesis of (1R∗,2R∗,3S∗)-1-acetoxymethyl-2,3,4,4-tetramethylcyclopentane 1, the sex pheromone of the obscure mealybug, Pseudococcus viburni, is described. The key step was diastereoselective catalytic hydrogenation of the tetrasubstituted double bond in 2,3,4,4-tetramethyl-cyclopent-2-enone 4 to give the thermodynamically less favored cis-2,3,4,4-tetramethyl-cyclopentanone
    描述了一种改进的非对映选择性合成的(1 R ∗,2 R ∗,3 S ∗)- 1-乙酰氧基甲基-2,3,4,4-四甲基环戊烷1(暗淡粉虱的性信息素,Pseudococcus viburni)。关键步骤是在2,3,4,4-四甲基-环戊-2-烯酮4中对四取代的双键进行非对映选择性催化加氢,得到热力学上较不受欢迎的顺式-2,3,4,4-四甲基-环戊酮3a。

  • Transition Metal Complex, Catalyst Composition Including the Same and Olefin Polymer Using Catalyst Composition
    申请人:Lee Choong Hoon
    公开号:US20070225158A1
    公开(公告)日:2007-09-27
    Provided are a novel transition metal complex where a monocyclopentadienyl ligand to which an amido group is introduced is coordinated, a catalyst composition including the same, and an olefin polymer using the catalyst composition. The transition metal complex has a pentagon ring structure having an amido group connected by a phenylene bridge in which a stable bond is formed in the vicinity of a metal site, and thus, a sterically hindered monomer can easily approach the transition metal complex. By using a catalyst composition including the transition metal complex, a linear low density polyolefin copolymer having a high molecular weight and a very low density polyolefin copolymer having a density of 0.910 g/cc or less can be produced in a polymerization of monomers having large steric hindrance. Further, the reactivity for the olefin monomer having large steric hindrance is excellent.
    提供了一种新型过渡金属配合物,其中包括一个含有氨基基团的单环戊二烯基配体,一个包括该配合物的催化剂组合物,以及使用该催化剂组合物的烯烃聚合物。该过渡金属配合物具有一个五边形环结构,其中通过苯基桥连接的氨基基团与金属位点附近形成稳定键,因此,立体位阻单体可以轻松接近该过渡金属配合物。通过使用包括该过渡金属配合物的催化剂组合物,在聚合具有较大立体位阻的单体时,可以生产具有高分子量的线性低密度聚烯烃共聚物和密度为0.910克/立方厘米或更低的超低密度聚烯烃共聚物。此外,对于具有较大立体位阻的烯烃单体,其反应性非常优秀。
