  π-酸催化烯丙基取代的对映选择性内酯化：π-烯丙基金属化学的补充

  摘要：

  不对称烯丙基烷基化 (AAA) 是形成非常有用的非外消旋烯丙基化合物的有效方法。在这里，我们提出了一种互补的对映选择性过程，该过程通过 π 酸催化生成烯丙内酯。更具体地说，报道了使用含有咪唑基P , N-配体 ( S )-StackPhos的新型 Pd II催化剂对烯丙醇进行催化对映选择性脱水内酯化。高产率反应操作简单，对映选择性高达 99 % ee. 该策略有助于用表面上更好的离去基团替换产品中的不良离去基团，避免因平衡外消旋化而引起的并发症。

  A series of estrogen receptor ligands based on a 3-alkyl naphthalene scaffold was synthesized using an intramolecular enolate-alkyne cycloaromatization as the key step. Several of these compounds bearing a C6-OH group were shown to be high affinity ligands. All compounds had similar ERalpha and ERbeta binding affinity ranging from micromolar to low nanomolar.

  Treatment of several omicron-alkynl-substituted alpha-diazoacetophenone derivatives with rhodium (II) carboxylates results in the formation of substituted indenones. The simplest mechanism accounting for the results involves addition of a rhodium-stabilized carbenoid onto the acetylenic pi-bond to generate a vinyl carbenoid directly of possibly a highly strained cyclopropene derivative. The vinyl carbenoid was found to undergo addition to a neighboring alkene tethered on the side chain to give an indenyl-substituted bicyclo[3.1.0]hexane derivative. A number of related systems were examined so as to probe the scope and generality of the process. Treatment of omicron-(6,8-nonadien-1-ynyl)-alpha-diazoacetophenone with rhodium (II) mandelate afforded a cyclopent[g]azulenone derivative. The formation of this compound involves a divinylcyclopropane intermediate that readily undergoes a Cope rearrangement under the reaction conditions. The rhodium-catalyzed reaction of 2-(6-oxo-1-hepty-nyl)-alpha-diazoacetophenone in the presence of N-phenylmaleimide afforded a mixture of two cycloadducts. One of the products can be accounted for in terms of a cyclization of the vinyl carbenoid onto the oxygen atom of the neighboring carbonyl group to give a resonance-stabilized dipole. 1,3-Dipolar cycloaddition of the carbonyl ylide across the activated pi-bond of N-phenylmaleimide affords the observed product. The second cycloadduct is formed by a 1,2-hydrogen shift of the initially produced vinyl carbenoid. The resulting diene undergoes a subsequent Diels-Alder reactions with N-phenylmaleimide.
