    Nitrogen Fixation: Synthesis of Heterocycles Using Molecular Nitrogen as a Nitrogen Source
    摘要:
    过渡金属固氮是一个迷人的过程。我们之前已经报道过使用Yamamoto报道的钛-氮配合物将分子氮引入有机化合物的方法。我们开发了一种新的钛催化氮化过程,使用TiCl4在过量Li和TMSCl的存在下进行。在这种反应中,可以使用1大气压的氮气,反应在室温下进行。这个过程非常简单。将TiCl4或Ti(OiPr)4(1 equiv.)、Li(10 equiv.)和TMSCl(10 equiv.)的THF溶液在氮气气氛下在室温下搅拌过夜,得到钛-氮配合物。尽管钛-氮配合物的结构尚未确定,但它们可能由N(TMS)3、X2TiN(TMS)2和XTi=NTMS组成。使用这种方法,可以通过钛配合物作为定量反应的单锅反应,以良好至中等的收率合成各种杂环化合物,如吲哚、喹啉、吡咯、吡咯啉和吲哚啉衍生物。此外,使用分子氮作为氮源合成了monomorine I和pumiliotoxin C。这种方法进一步扩展,用于使用催化量的钛配合物合成杂环化合物;此外,以高收率获得了吲哚和吡咯衍生物。

  • A sustainable catalytic pyrrole synthesis
    作者:Stefan Michlik、Rhett Kempe

    日期:2013.2
    The pyrrole heterocycle is a prominent chemical motif and is found widely in natural products, drugs, catalysts and advanced materials. Here we introduce a sustainable iridium-catalysed pyrrole synthesis in which secondary alcohols and amino alcohols are deoxygenated and linked selectively via the formation of C–N and C–C bonds. Two equivalents of hydrogen gas are eliminated in the course of the reaction, and alcohols based entirely on renewable resources can be used as starting materials. The catalytic synthesis protocol tolerates a large variety of functional groups, which includes olefins, chlorides, bromides, organometallic moieties, amines and hydroxyl groups. We have developed a catalyst that operates efficiently under mild conditions. Pyrroles are a highly important class of compounds with a wide variety of applications in biochemistry, pharmacy and materials science. Here, an iridium-catalysed synthesis of pyrroles is described, starting from renewable resources, alcohols that may be derived from lignocellulosic feedstocks and amino alcohols. The reaction proceeds by a condensation reaction that liberates two equivalents of hydrogen gas.
    吡咯杂环是一种突出的化学基元,广泛存在于天然产物、药物、催化剂和先进材料中。本文介绍了一种可持续的铱催化吡咯合成方法,该方法通过形成C–N和C–C键,选择性地对二级醇和氨基醇进行脱氧耦合。反应过程中消除了两当量的氢气,并且可以完全使用可再生资源衍生的醇作为起始原料。催化合成方案能够耐受多种官能团,包括烯烃、氯化物、溴化物、有机金属基团、胺和羟基等。我们开发了一种在温和条件下高效运作的催化剂。吡咯是一类具有广泛应用的重要化合物,涉及生物化学、药物学和材料科学等领域。本文描述了一种从可再生资源出发,铱催化的吡咯合成方法,起始原料为来自木质纤维素原料的醇和氨基醇。该反应通过缩合反应释放两当量的氢气。

    Molybdenum-based efficient and broadly applicable catalytic system is presented for the dehydrogenative coupling of γ-/β-amino alcohols with ketones. In particular, complex Mo(CO)6 in combination with Xantphos and t-BuOK as base provides direct synthesis of structurally diverse quinoline, pyridine, and pyrrole compounds (total 55 examples) with isolated yields up to 92%. Low catalyst loading, cost-effective

    Nitrogen fixation using transition metals is a fascinating process. We have already reported on the incorporation of molecular nitrogen into organic compounds using a titanium–nitrogen complex reported by Yamamoto. We developed a novel titanium-catalyzed nitrogenation procedure using TiCl4 in the presence of an excess amount of Li and TMSCl. In this reaction, a 1 atm pressure of nitrogen gas can be used and the reaction proceeds at room temperature. The procedure is very simple. A THF solution of TiCl4 or Ti(OiPr)4 (1 equiv.), Li (10 equiv.), and TMSCl (10 equiv.) was stirred under an atmosphere of nitrogen at room temperature overnight to give titanium–nitrogen complexes. Although the structures of the titanium–nitrogen complexes have not yet been determined, they would consist of N(TMS)3, X2TiN(TMS)2, and XTi=NTMS. Using this procedure, various heterocycles, such as indole, quinoline, pyrrole, pyrrolizine, and indolizine derivatives, could be synthesized from molecular nitrogen in good-to-moderate yields as a stoichiometric reaction based on a titanium complex by a one-pot reaction. Furthermore, monomorine I and pumiliotoxin C were synthesized from molecular nitrogen as a nitrogen source. This procedure was further extended for the syntheses of heterocycles using a catalytic amount of titanium complex; also, indole and pyrrole derivatives were obtained in high yields.
