    reactions with a tandem hydroformylation-Fischer indole synthesis sequence as a highly diversity-oriented strategy for the synthesis of tryptamines and homologues was explored. This modular approach allows the substituents at C3 of the indole core, the type of the amine moiety, and the distance of the amine moiety to the indole core in the final synthetic step to be defined. The starting materials required
    探讨了对映选择性烯丙基化反应与串联加氢甲酰化-Fischer吲哚合成序列的组合,作为一种高度多样化的策略,用于合成色胺和同源物。通过这种模块化方法,可以定义最终合成步骤中吲哚核的C3处的取代基,胺部分的类型以及胺部分与吲哚核的距离。加氢甲酰化步骤所需的起始原料是通过铱催化的对映选择性烯丙基取代反应以高收率和优异的对映选择性合成的。在苯基肼的存在下,Rh催化的加氢甲酰化步骤使原位形成的醛被捕获为trap。
  • Mechanistic Studies on Pd-Catalyzed Telomerization and Co-Cyclization of Butadiene: Amphiphilicity of Bis-π-allylpalladium Intermediate in the Presence of Phosphine Ligand
    作者:Jitsuo Kiji、Tamon Okano、Takaaki Nomura、Kayoko Saiki、Torei Sai、Jiro Tsuji

    日期:2001.10
    Pd-catalyzed reactions of butadiene, which proceed through a bis-π-allylpalladium intermediate, (η3,η3-C8H12)Pd (2), were performed in the presence of both a pronucleophile (aceto- or cyanoacetate) and an electrophile (benzaldehyde). Methyl aceto- or cyanoacetate and benzaldehyde reacted independently with 2 to give telomers 8 and the divinyl-substituted pyranes 9, respectively. In the case of methyl cyanoacetate, the co-cyclization of 2 with 2-cyano-3-phenylpropenoate (11) formed in situ also took place to afford the cyclohexane derivative 10. Namely, three kinds of amphiphilic additions of the C8-chain of 2 occurred to δ+H–Nuδ−, δ+C=Cδ−, and δ+C=Oδ− simultaneously in a one-pot reaction. The Pd-catalyzed reaction of allyl chloride, allyltributylstannane, methyl cyanoacetate, and benzaldehyde was undertaken under neutral conditions, expecting the amphiphilic reactions by the intermediacy of (η3-C3H5)2Pd (6) formed in situ. Allylation of both benzaldehyde and methyl cyanoacetate took place. Competitively amphiphilic bis-allylation of the polar double bond of 11 also occurred to form the 1,7-octadiene derivative 18. The mechanisms of both reactions can be explainable in terms of the amphiphilicity of the intermediates (2 and 6) in the presence of a phosphine ligand.
    在乙酸或氰乙酸作为亲核试剂和苯甲醛作为亲电试剂的存在下,通过双π-烯丙基金属中间体(η3,η3-C8H12)Pd(2)进行的钯催化丁二烯反应分别生成了8聚体和二乙烯基取代的吡喃9。对于氰乙酸甲酯的情况下,由2与现场生成的2-氰基-3-苯基丙烯酸酯(11)进行的共环化反应也同时发生,形成了环己烷衍生物10。也就是说,在单锅反应中,同时发生了C8链的2对δ+H–Nuδ−、δ+C=Cδ−和δ+C=Oδ−亲油性加成的三种类型反应。在无碱性条件下,利用现场生成的(η3-C3H5)2Pd(6)作为中间体,进行了三氯甲硅烷丙烯、三丁基锡丙烯、氰乙酸甲酯和苯甲醛的钯催化反应。苯甲醛和氰乙酸甲酯都发生了丙烯基化反应。极性双键11也通过竞争性的亲油性双丙烯基化反应形成了1,7-辛二烯衍生物18。这两种反应的机理都可以在存在磷配体的情况下,根据中间体(2和6)的亲油性进行解释。
  • Unconventional Reactivity of a Grubbs Catalyst: Hydroalkylation Overriding Metathesis
    作者:Amit Singh Adhikari、Nilanjana Majumdar
    DOI:10.1021/acs.orglett.3c03456
    日期:2023.12.8
    Unprecedented reactivity of a Grubbs catalyst has been disclosed in a reaction between vinyl azaarenes and alkenylnitriles under standard metathesis conditions. No metathesis was observed; only hydroalkylation products were obtained in high yields. The practical utility of this method has been demonstrated by the application of the products in useful transformations, e.g., the formation of cyclic iminoesters
    在标准复分解条件下,乙烯基氮杂芳烃和烯基腈之间的反应中揭示了格鲁布斯催化剂前所未有的反应活性。没有观察到复分解作用;仅以高收率获得加氢烷基化产物。该方法的实用性已通过产品在有用转化中的应用得到证明,例如环状亚氨基酯和极具挑战性的中等碳环的形成。

    Atom transfer radical addition (ATRA) reactions are crucial for the dual functionalization of unsaturated hydrocarbons. Radical generation, pivotal in ATRA, has seen advancements from thermal to photochemical methods. Recent focus on halogen-bonding-based radical generation, including our group’s innovative photochemical approach, offers cost-effective alternatives to transition-metal-dependent photocatalysts
