  • Non-Catalyzed Thermal Reactions of Acylquinones with Allylstannanes
    作者:Kazuhiro Maruyama、Yoshihiro Matano
    DOI:10.1246/bcsj.62.3877
    日期:1989.12
    Thermal reactions of acylquinones with allylstannanes in benzene afforded several kinds of product after column chromatography on silica gel; acyl allyl quinones, acyl allyl epoxy quinones, cyclopentanoid compounds including stannyl moiety, allyl hydroxy quinones, acyl hydroquinones, and acyl allyl hydroquinones. The main product comprises cyclopentanoid compounds, which are novel [2+3] cyclo adducts with 1,2-migration of trialkylstannyl moiety. Spectroscopic examinations (1H NMR and Vis-UV) enabled us to confirm the reaction pathways that four types of precursors were initially generated via polarized tight pair and inverted to isolated products during purification by column chromatography. Similar reactions in acetonitrile showed a remarkable difference in the reactivity, that is, acyl allyl quinones and the corresponding hydroquinones are obtained, but the [2+3] cyclo adducts are not produced at all. From 1H NMR examination, it was confirmed that three types of precursor are generated via solvent separated ion pairs at the initial stage. The rather strong reactivity of acylquinones towards allylstannanes will be due to electron withdrawing ability of acyl group.
    酰基喹诺酮与烯丙基锡在苯中的热反应经过硅胶柱层析后产生了几种产品;包括酰基烯丙基喹诺酮、酰基烯丙基环氧喹诺酮、含锡基团的环戊烷类化合物、烯丙基羟基喹诺酮、酰基羟基喹诺酮和酰基烯丙基羟基喹诺酮。主要产品是环戊烷类化合物,它们是新型的 [2+3] 环加成物,具有三烷基锡基团的 1,2-迁移。通过光谱学检查(1H NMR 和 Vis-UV),我们确认了反应途径,四种前体最初通过极化紧配对生成,并在柱层析纯化过程中转化为孤立的产品。在乙腈中的类似反应显示出明显的反应性差异,即生成酰基烯丙基喹诺酮及其对应的羟基喹诺酮,但完全不产生 [2+3] 环加成物。从 1H NMR 检查中确认,三种类型的前体在初始阶段通过溶剂分离离子对生成。酰基喹诺酮对烯丙基锡的较强反应性将是由于酰基的电子吸引能力。
  • Using Neighboring-Group Participation for Acyclic Stereocontrol in Diastereoselective Substitution Reactions of Acetals
    作者:Amanda Ramdular、K. A. Woerpel
    DOI:10.1021/acs.orglett.0c01166
    日期:2020.6.5
    Neighboring-group participation of an ester enabled stereocontrol in substitution reactions of acyclic acetals. The ester group formed a trans-fused dioxolenium ion intermediate, which underwent a substitution reaction at the acetal carbon atom to afford the product with high diastereoselectivity. Neighboring-group participation was confirmed by isolating dioxolane products resulting from nucleophilic
    酯的邻近基团的参与使得能够在无环缩醛的取代反应中实现立体控制。酯基形成反式稠合二氧杂环烯离子中间体,在缩醛碳原子上发生取代反应,得到具有高非对映选择性的产物。通过分离由 1,3-二氧杂环戊烯离子中间体的 C-2 亲核加成产生的二氧戊环产物来证实邻近基团的参与。使用新戊酸酯作为参与基团与强亲核试剂结合产生非对映选择性≥90:10的取代产物。
  • Sulfur dioxide insertion into carbontin bonds
    作者:Clifford W. Fong、William Kitching
    DOI:10.1016/s0022-328x(00)83081-8
    日期:1970.3
    A number of allylic, allenylic and 2-propynylic (R′) derivatives of tin of the type R3SnR′ have been synthesized, and shown to undergo ready insertion of sulfur dioxide into the SnR′ bond. Rearrangement accompanies insertion so that the products have the alternate allylic, 2-propynylic and allenylic structures respectively. Di-insertion occurs only when groups attached to tin are quite susceptible

    作者:Olivier Desponds、Manfred Schlosser
    DOI:10.1016/0022-328x(91)86134-c

    alkylbenzenes and subsequent condensation with trialkylstannyl chloride affords allyl- or benzyl-type organotin compounds that can be isolated in pure form. Treatment with soluble reagents such as methyllithium, trimethylsilylmethylpotassium and trimethylsilylmethylcaesium generates the corresponding organoalkali derivatives almost quantitatively and in high purity, suitable for kinetic or spectroscopic studies
