  indium-mediated additions, solvent plays a major role in determining the nature of the organoindium intermediate and we observed the susceptibility of some allylindium intermediates to hydrolysis in protic solvents. Under our reaction conditions using a polar aprotic solvent, we suggest that an allylindium(III) species is the active allylating intermediate. In addition, we have observed the presence of

  我们报告了一种简单，有效且通用的方法，用于在一锅合成中在Barbier型条件下进行芳香族和脂肪族醛和酮的铟介导的对映选择性烯丙基化，可提供非常好的收率的手性醇产品（高达99％ ）和对映体过量（最高93％）。我们的方法能够耐受各种官能团，例如酯，腈和酚。此外，当使用肉桂基溴化物（> 95/5 anti / syn）时，可以使用更多取代的烯丙基溴，例如巴豆基和肉桂基溴化物，提供中等的对映选择性（分别为72％和56％）和出色的非对映选择性。）。然而，使用巴豆基溴化物时的立体选择性差，并且在我们的方法下，其他官能化的烯丙基溴化物对醇产物的对映选择性低。在这些类型的铟介导的添加物中，溶剂在确定有机铟中间体的性质中起主要作用，我们观察到某些烯丙基铟中间体对质子溶剂水解的敏感性。在使用极性非质子传递溶剂的反应条件下，我们认为烯丙基（III）物种是活性烯丙基化中间体。此外，我们已经观察到整个反应过程中存在

  groups to aldehydes and ketones using B-chlorodiisopinocampheylborane (dDIP-Cl) and indium metal. Under Barbier-type conditions, indium metal was used to generate allyl- and allenylindium intermediates, and subsequent reaction with dDIP-Cl successfully promoted the transfer of these groups to boron forming the corresponding chiral borane reagents. The newly formed borane reagents were reacted with aldehydes

  我们报告了第一个一锅法，用于使用B-氯二异opinocampheylborane（d DIP-Cl）和铟金属将烯丙基，甲基烯丙基和炔丙基不对称加成到醛和酮上。在Barbier型条件下，使用铟金属生成烯丙基和烯丙基铟中间体，然后与d反应DIP-Cl成功地促进了这些基团向硼的转移，形成了相应的手性硼烷试剂。使新形成的硼烷试剂与醛和酮反应，以高收率和高达出色的对映选择性（98％ee）生产相应的醇产物。该方法由苯甲醛的烯丙基化和甲基烯丙基化反应产生了极佳的对映体富集的仲均烯丙基醇。使用这种方法，酮的甲基化和肉桂基化提供了最高的对映选择性，而醛和酮的炔丙基化则提供了低的对映体过量。另外，该方法提供了B-烯基二异opinocampheylborane的第一个合成，其特征在于1 H和11B NMR光谱。这是直接合成烯丙基硼烷的第一个例子，该烯丙基硼烷包含来自相应的烯丙基溴和铟的取代基，从而扩展了DIP-

  (S)-3,3'-F-2-BINOL has been synthesized for the first time and demonstrated as a highly active organocatalyst for asymmetric methallylation of ketones. Up to 98:2 enantioselectivity and 99% yield were obtained with 5 mol % catalyst loading. The catalyst (S)-3,3'-F-2-BINOL could be easily recovered and reused.
• Catalytic Asymmetric Methallylation of Ketones with an (H₈-BINOLate)Ti-Based Catalyst
  作者：Jeung Gon Kim、Elizabeth H. Camp、Patrick J. Walsh

  DOI：10.1021/ol061417y

  日期：2006.9.1

  The first catalytic asymmetric methallylation of ketones is reported. The catalyst, which is generated from titanium tetraisopropoxide, H-8-BINOL, 2-propanol, and tetramethallylstannane, reacts with ketones in acetonitrile to afford tertiary homoallylic alcohols in fair to excellent yields (55-99%) and fair to high enantioselectivities (46-90%). Ozonolysis of the resulting products provides access to chiral, ss-hydroxy ketones, which are not readily prepared from direct asymmetric aldol reaction of acetone with ketones.
