  • Reactions of 1,2-Diketones with Vinyllithium: Addition Reactions and Dianionic Oxy Cope Rearrangements of Cyclic and Acyclic Substrates
    作者:Christian Clausen、Rudolf Wartchow、Holger Butenschön

    substrates, this reaction sequence was also found, albeit with somewhat lower yields and requiring higher temperatures than in the benzil cases. A brief investigation of the intramolecular aldol adduct/1,6-hexanedione equilibrium indicated that the preferential formation of intramolecular aldol adducts at lower temperatures and at shorter reaction times appears to be the result of kinetic reaction control,
    已显示出在低温下将烯基锂衍生物同步双加成到环丁二酮化合物(例如苯并环丁烯二酮铬配合物 1 或方酸酯)中时会发生双阴离子氧基 Cope 重排。为了深入了解这种类型的反应序列在这些特殊情况之外的更普遍的适用性,用乙烯基锂处理了许多 1,2-二酮。测试的二酮包括苄基衍生物、脂肪族无环 1,2-二酮、邻苯醌和环状脂肪族 1,2-二酮。对于苄基和杂苄基衍生物,发现所需的双加成/双阴离子氧基 Cope 重排在低温下发生,导致 1,6-二酮及其分子内醛醇加合物的总产率高达 80%。以无环脂肪族 1,2-二酮为底物,也发现了这种反应顺序,尽管与苄基反应相比,产率略低且需要更高的温度。对分子内醛醇加合物/1,6-己二酮平衡的简要研究表明,在较低温度和较短反应时间下优先形成分子内醛醇加合物似乎是动力学反应控制的结果,而对 1,6-较高温度下的二酮是由热力学反应控制引起的。邻醌仅通过加成与乙烯基锂反应;没有观察到双阴离子氧
  • Neighboring Group Participation by Heteroaromatic Rings: The Wagner–Meerwein Type Skeletal Rearrangement in the Electrophilic Addition Reactions of Norbornadiene-Fused Furans, Pyrroles, and Thiophenes
    作者:Tomoshige Kobayashi、Takeo Tsuzuki、Mayu Saitoh
    DOI:10.1246/bcsj.72.1597
    日期:1999.7
    The electrophilic addition reactions of norbornadiene-fused furans, pyrroles, and thiophenes with bromine, arenesulfenyl chlorides, or a triazoledione generally afforded skeletally rearranged adducts except for a dibenzoyl-substituted thiophene. The formations of the adducts are attributable to the neighboring group participation by five-membered heteroaromatic rings, accompanied by the formations
    降冰片二烯稠合的呋喃、吡咯和噻吩与溴、芳烃亚磺酰氯或三唑二酮的亲电加成反应通常提供骨架重排的加合物,但二苯甲酰基取代的噻吩除外。加合物的形成归因于五元杂芳环的相邻基团参与,伴随着桥连杂芳烃离子的形成和随后的 Wagner-Meewein 型骨架重排。

    meso-α-dicarbonyl compounds with chiral phosphonate reagents, which possessed axially dissymmetric 1,1′-bi-2- or 8-naphthol at the carboxylate moiety as a chiral auxiliary, were examined. The reactions proceeded smoothly with good chemical yields as well as with high diastereoselectivities. Z-olefins were preferentially formed, and it was found that the free hydroxy group at the 2′- or 8′-position on the naphthalene
    考察了选定的内消旋-α-二羰基化合物与手性膦酸酯试剂的非对称霍纳-沃兹沃思-埃蒙斯反应,该手性膦酸酯试剂在羧酸盐部分具有轴向不对称的1,1'-bi-2-或8-萘酚作为手性助剂。反应顺利进行,化学收率高,非对映选择性高。Z-烯烃优先形成,并且发现萘环上2'-或8'-位的游离羟基在高非对映选择性中起着至关重要的作用,这可能是由于络合物诱导的邻近效应所致。还介绍了机械方面的考虑。
  • Neighboring effect by heteroaromatic rings: formation of skeletally rearranged adducts by cycloaddition reaction of norbornadiene-fused pyridazines and pyrazines with 4-phenyl-1,2,4-triazole-3,5(4H)-dione
    作者:Tomoshige Kobayashi、Kiyomi Miki、Behrooz Nikaeen、Hideaki Baba
    DOI:10.1016/s0040-4020(99)00821-2
    日期:1999.11
    Norbornadiene-fused pyridazines and pyrazines reacted with 4-phenyl-1, 2,4-triazole-3,5(4H)-dione to give skeletally rearranged adducts in moderate yields. A similar reaction with fused pyridazine N-oxides or a fused pyrazine N-oxide resulted in the regioselective formation of the rearranged adduct. The formations of the skeletally rearranged adducts would be ascribed to the intervention of bridged
    降冰片二烯稠合的哒嗪和吡嗪与4-苯基-1,2,4-三唑-3,5(4 H)-二酮反应,以中等收率生成骨架重排的加合物。与稠合的哒嗪N-氧化物或稠合的吡嗪N-氧化物的类似反应导致重排加合物的区域选择性形成。骨架重排的加合物的形成归因于杂芳环的相邻基团参与形成的桥接杂芳烃离子中间体的干预。
  • Norbornadiene-Fused Heterocycles: Synthesis and Bromination Reaction of 5,8-Dihydro-5,8-methanoquinoxaline Derivatives
    作者:Tomoshige Kobayashi、Kiyomi Miki
    DOI:10.1246/bcsj.71.1443
    日期:1998.6
    A norbornadiene-fused pyrazine was prepared by the condensation reaction of bicyclo[2.2.1]hept-5-ene-2,3-dione with ethylenediamine followed by oxidation. Treatments of the norbornadiene-fused pyrazine and its benzo derivative with bromine in carbon tetrachloride or in dioxane afforded trans-adducts as major products, accompanied by the formations of cis-adducts and dibromo derivatives derived from Wagner–Meerwein type skeletal rearrangement, while bromination of a fused dicyanopyrazine in carbon tetrachloride gave only a trans-adduct. In contrast, a fused pyrazine with an electron-donating N-oxide group gave a 7,9-dibromo derivative as the main component. The possibility of the intervention of a 2H-pyrazinium ion for the formation of the skeletally rearranged products is discussed together with the results of ab-initio (3-21G*) calculations.
    双环[2.2.1]庚-5-烯-2,3-二酮与乙二胺发生缩合反应并氧化,制备出一种降冰片二烯融合吡嗪。在四氯化碳或二噁烷中用溴处理降冰片二烯融合吡嗪及其苯并呋喃衍生物时,主要产物为反式加合物,同时形成顺式加合物和由瓦格纳-梅尔韦恩型骨架重排衍生的二溴衍生物,而在四氯化碳中溴化融合二氰基吡嗪时,只产生反式加合物。与此相反,带有一个供电子的 N-氧化基团的融合吡嗪的主要成分是一种 7,9-二溴衍生物。本文结合非原位(3-21G*)计算的结果,讨论了 2H 吡嗪离子参与形成骨架重排产物的可能性。
