  • Iron catalyzed cross coupling reactions of aromatic compounds
    申请人:——
    公开号:US20030220498A1
    公开(公告)日:2003-11-27
    A process for the production of compounds Ar—R 1 by means of a cross-coupling reaction of an organometallic reagent R 1 —M with an aromatic or heteroaromatic substrate Ar—X catalyzed by one or several iron salts or iron complexes as catalysts or pre-catalysts, present homogeneously or heterogeneously in the reaction mixture. This new invention exhibits substantial advantages over established cross coupling methodology using palladium- or nickel complexes as the catalysts. Most notable aspects are the fact that (i) expensive and/or toxic nobel metal catalysts are replaced by cheap, stable, commercially available and toxicologically benign iron salts or iron complexes as the catalysts or pre-catalysts, (ii) commercially attractive aryl chlorides as well as various aryl sulfonates can be used as starting materials, (iii) the reaction can be performed under “ligand-free” conditons, and (iv) the reaction times are usually very short.
    通过使用一种或多种铁盐或铁络合物作为催化剂或前催化剂,在有机金属试剂R1—M与芳香或杂芳底物Ar—X之间进行交叉偶联反应的方法,生产化合物Ar—R1。这一新发明相对于使用钯或镍络合物作为催化剂的传统交叉偶联方法具有显著优势。最值得注意的方面包括:(i) 昂贵和/或有毒的贵金属催化剂被廉价、稳定、商业可获得且毒理学上良性的铁盐或铁络合物替代作为催化剂或前催化剂,(ii) 商业上具吸引力的芳基氯化物以及各种芳基磺酸盐可用作起始材料,(iii) 反应可在“无配体”条件下进行,(iv) 反应时间通常非常短。
  • Dilithium Amides as a Modular Bis-Anionic Ligand Platform for Iron-Catalyzed Cross-Coupling

    Dilithium amides have been developed as a bespoke and general ligand for iron-catalyzed Kumada–Tamao–Corriu cross-coupling reactions, their design taking inspiration from previous mechanistic and structural studies. They allow for the cross-coupling of alkyl Grignard reagents with sp2-hybridized electrophiles as well as aryl Grignard reagents with sp3-hybridized electrophiles. This represents a rare
    氨基二锂已被开发为铁催化的 Kumada-Tamao-Corriu 交叉偶联反应的定制和通用配体,其设计灵感来自先前的机械和结构研究。它们允许烷基格氏试剂与 sp 2杂化亲电试剂以及芳基格氏试剂与 sp 3杂化亲电试剂交叉偶联。这代表了一个罕见的例子,即单一铁催化系统在不同的偶联反应中有效,而无需对催化方案进行重大修改,并且操作简单。

    and -CF(3) groups are compatible. The method also allows for consecutive cross-coupling processes in one pot, as exemplified by the efficient preparation of compound 12, and has been applied to the first synthesis of the cytotoxic marine natural product montipyridine 8. In contrast to the clean reaction of (hetero)aryl chlorides, the corresponding bromides and iodides are prone to a reduction of their
    简单的铁盐,如 FeCl(n)、Fe(acac)(n) (n = 2,3) 或 salen 络合物 4 被证明是高效、廉价、毒理学无害且环境友好的预催化剂,可用于许多交叉- 烷基或芳基格氏试剂、锌酸盐或有机锰物质与芳基和杂芳基氯化物、三氟甲磺酸盐甚至甲苯磺酸盐的偶联反应。原位制备的正式成分 [Fe(MgX)(2)] 的“无机格氏试剂”可能构成负责催化周转的传播物种,在许多情况下,即使在室温或室温以下,这种转化率也以前所未有的速度发生。由于反应条件异常温和,一系列官能团如酯、醚、腈、磺酸盐、磺酰胺、硫醚、缩醛、炔烃和 -CF(3) 基团是相容的。

    part of a vaccine. Here, we report the first asymmetric total synthesis of 1. Two approaches were developed for the synthesis of hydroxyphthioceranic acid (4), its polypropionate part, thereby establishing the absolute stereochemistry of the C17 hydroxyl function to be of (R)-configuration. Subsequently, 4 was regioselectively connected to the trehalose core and after selective sulfation and a final
    结核分枝杆菌(TB)的病原体结核分枝杆菌继续代表具有挑战性的病原体,导致许多人死亡。该病原体持续存在的原因是细胞包膜成分,它由长尾(糖)脂质组成,参与宿主免疫应答的调节。在细胞被膜中发现的二酰化磺基糖脂Ac 2 SGL(1)是一种有效的抗原,可刺激针对TB的免疫反应。该观察结果表明将1作为疫苗的一部分使用。在这里,我们报告的第一不对称全合成1。开发了两种方法合成羟基苯硫醚酸(4),其聚丙烯酸酯部分,从而确定C17羟基官能团的绝对立体化学为(R)-构型。随后,将4个区域选择性地连接至海藻糖核,并且在选择性硫酸化和最后的四倍脱保护步骤之后,获得纯的1。合成和天然1的身份已通过NMR和质量分析证实,此外,合成1的生物学功能与1相同,并激活了对1的最小结构修饰高度敏感的CD1b限制性和Ac 2 SGL特异性T细胞。具有相同的效力。提出了模型研究以指出1的结构特征,这些特征对于与抗原呈递分子CD1b和T细胞受体的结合很重要。

    Synthetic routes to forty-four dibenzocrown ether alcohols are reported. The new crown ether com pounds are based on a sym-dibenzo-16-crown-5 platform. Most have a hydroxy group and an alkyl, aryl, aralkyl, alkenyl, alkynyl, or perfluoroalkyl group on the central carbon of the three-carbon bridge. Others have substituted benzene rings and either a hydroxy or -O(CH2)nOH group attached to the central
