  • Tripodal trisamides based on nicotinic and picolinic acid derivatives
    作者:H R Hoveyda、Veranja Karunaratne、Christopher J Nichols、Steven J Rettig、Ashley KW Stephens、Chris Orvig
    DOI:10.1139/v98-030
    日期:1998.4.1

    A number of polydentate arylamide ligands have been prepared by coupling various acyclic tripodal or linear polyamines with derivatives of nicotinic and picolinic acids. Two synthetic procedures were utilized; tris[(2-hydroxynicotinyl)carbonyl]-2-aminoethyl}amine (H3NICTREN) was prepared by Method A, the HOSu/DCC method, and the other arylamides in this study were prepared by Method B, the CDI method. Method A involved the reaction of N-hydroxysuccinimide with 2-hydroxynicotinic acid (in the presence of dicyclohexylcarbodiimide (DCC) as a dehydrative coupling reagent) to form the succinimide ester, followed by reaction with TREN to yield H3NICTREN. Method B involved reaction of a carboxylic acid (2-hydroxynicotinic, 3-hydroxypicolinic, nicotinic, or picolinic acids) with carbonyldiimidazole (CDI) to form the N-acylimidazolide, followed by reaction with the amine (TREN, TAME, spermidine, or TRPN) to yield the desired arylamide. The X-ray structure of 1,1,1-tris[(3-hydroxypicolinyl)carbonyl]-2-aminomethyl}ethane (H3PICTAME) was determined; crystals of H3PICTAME are monoclinic, a = 10.257(2), b = 15.572(3), c = 15.208(2) Å, β = 96.124(15)°, Z = 4, space group P21/a. The structure was solved by direct methods and refined by full-matrix least-squares procedures to R = 0.041 and Rw = 0.038 for 2506 reflections with I >= 3 sigma (I). In the solid state, H3PICTAME contains an extensive hydrogen-bonding network, with eight intra- and one intermolecular H-bonds per molecule; the ligand is partially preorganized for metal ion chelation. The acid dissociation constants of H3NICTREN and those of 1,1,1-tris[(2-hydroxynicotinyl)carbonyl]-2-

    aminomethyl}ethane (H3NICTAME) have been determined; pKa1 = 11.2 (10.68), pKa2 = 10.7 (10.58), pKa3 = 10.0 (9.71), and pKa4 = 6.25 for H3NICTREN (H3NICTAME); the high phenolic pKa's are consistent with the hydrogen bonding observed in the solid state.Key words: arylamide, hydrogen bonding, preorganization.

    一些多齿芳胺配体已通过将各种无环三脚架或线性多胺与烟酸和吡啶甲酸衍生物偶联而制备。本研究采用了两种合成方法;三[(2-羟基烟酰基)羰基]-2-氨基乙基}胺(H3NICTREN)通过方法A,即HOSu/DCC方法制备,而本研究中的其他芳胺通过方法B,即CDI方法制备。方法A涉及N-羟基琥珀酰亚胺与2-羟基烟酸(在二环己基碳二亚胺(DCC)存在下作为脱水偶联试剂)反应形成琥珀酰亚胺酯,然后与TREN反应生成H3NICTREN。方法B涉及羧酸(2-羟基烟酸、3-羟基吡啶甲酸、烟酸或吡啶甲酸)与羰基二咪唑(CDI)反应形成N-酰基咪唑,然后与胺(TREN、TAME、精胺或TRPN)反应生成所需的芳胺。确定了1,1,1-三[(3-羟基吡啶基)羰基]-2-氨基甲基}乙烷(H3PICTAME)的X射线结构;H3PICTAME的晶体为单斜晶系,a = 10.257(2),b = 15.572(3),c = 15.208(2) Å,β = 96.124(15)°,Z = 4,空间群P21/a。该结构通过直接方法解决,并通过全矩阵最小二乘法精化至R = 0.041和Rw = 0.038,对于I >= 3 sigma (I)的2506个反射。在固态中,H3PICTAME包含广泛的氢键网络,每个分子有八个分子内和一个分子间氢键;配体部分预组织以供金属离子螯合。已确定了H3NICTREN和1,1,1-三[(2-羟基烟酰基)羰基]-2-氨基甲基}乙烷(H3NICTAME)的酸解离常数;H3NICTREN(H3NICTAME)的pKa1 = 11.2(10.68),pKa2 = 10.7(10.58),pKa3 = 10.0(9.71),pKa4 = 6.25;高酚pKa值与固态中观察到的氢键结合一致。关键词:芳胺,氢键,预组织。

    Two different ways to carry out the chemoselective acylation of 2-amino-8-quinolinol with unique features to generate C2-amides or C8-esters were developed. The coupling reaction with a variety of carboxylic acids using EDCI and DMAP provided C8-ester derivatives, whereas N-heteroaromatic acids were not introduced on the C8-hydroxy group, but rather on the C2-amino group under the same conditions.
    开发了两种不同的方法来进行具有独特特征的2-氨基-8-喹啉醇的化学选择性酰化反应,以生成C2-酰胺或C8-酯。使用EDCI和DMAP与多种羧酸的偶联反应提供了C8-酯衍生物,而在相同条件下,N-杂芳族酸没有引入C8-羟基上,而是引入了C2-氨基上。为了选择性地获得C 2-酰胺,将来自2-氨基-8-喹啉醇的阴离子亲核试剂用反应性较小的酰基咪唑啉化物或酯处理。

    a state-of-the-art methodology enabling radical–radical coupling. The catalytic process involves forming an acyl azolium intermediate from the NHC catalyst and an acyl donor, followed by single electron reduction of this key intermediate, which is largely dependent on the photoredox catalyst. We designed a radical NHC catalysis in which the direct photoexcitation of a borate to form a high reducing
    自由基-自由基偶联是两种不同自由基物种之间的选择性反应,有助于连接大单元的方法。光驱动N-杂环卡宾(NHC)有机催化被认为是一种最先进的方法,能够实现自由基-自由基偶联。催化过程包括从 NHC 催化剂和酰基供体形成酰基唑中间体,然后对该关键中间体进行单电子还原,这在很大程度上取决于光氧化还原催化剂。我们设计了一种自由基 NHC 催化,其中硼酸盐的直接光激发形成高还原剂促进了单电子还原事件。硼酸盐为单电子转移过程产生烷基自由基以完成自由基-自由基偶联。除了烯烃与烷基硼酸盐和酰基咪唑的自由基中继型烷基酰化外,该协议还可以实现烷基硼酸盐和酰基咪唑之间的交叉偶联,从而提供范围广泛的酮。

    A convenient method is disclosed for the synthesis of both 3-hydroxyisoquinolines and 2-hydroxy-1,4-naphthoquinones from β-ketoesters using a one-pot aryne acyl-alkylation/condensation procedure. When performed in conjunction with a one-step method for the synthesis of the β-ketoester substrates, this method provides a new route to these polyaromatic structures in only two steps from commercially available carboxylic acid starting materials. The utility of this approach is demonstrated in the synthesis of the atropisomeric P,N-ligand, QUINAP.
