  • De novo synthesis of bacteriochlorins
    申请人:Kim Han-Je
    公开号:US20060194960A1
    公开(公告)日:2006-08-31
    A method of making a bacteriochlorin is carried out by condensing a pair of compounds of Formula II to produce the bacteriochlorin, wherein R is an acetal or aldehyde group. The condensing may be carried out in an organic solvent, preferably in the presence of an acid. The bacteriochlorins are useful for a variety of purposes such as active agents in photodynamic therapy, luminescent compounds in flow cytometry, solar cells, light harvesting arrays, and molecular memory devices.
    通过将式II的一对化合物缩合产生细菌叶绿素的方法进行,其中R是缩醛或醛基团。缩合可以在有机溶剂中进行,最好在酸的存在下进行。细菌叶绿素可用于各种用途,如光动力疗法中的活性剂、流式细胞术中的发光化合物、太阳能电池、光收集阵列和分子存储器件。

    dimethoxymethyl, oxo, methoxy, methylthio, iminomethyl, ethoxycarbonylvinyl, dicyanovinyl) substituents have been prepared and examined in the directed synthesis of bacteriochlorins. The routes – inspired by a directed route to chlorins – rely on condensation of two hydrodipyrrins to produce a hydrobilin followed by ring closure to form the macrocycle. Four new unsymmetrically substituted bacteriochlorins
    还原的四吡咯化学作用不如完全不饱和的(卟啉)类似物,但鉴于卟啉的天然作用(例如,,叶绿素,细菌叶绿素)和收缩型卟啉胺素)。1-(二甲氧基甲基)-2,3-二氢-3,3-二甲基联吡啶(称为二氢联吡啶-乙缩醛)的自缩合提供了相应的细菌二氢卟啉或四氢脱氢corrin,其结果可能通过选择催化条件来控制。在仿生研究中,必须在合成大环的周围安装不同类型的取代基,这是必不可少的。在此,有18种新的靶标(和9种中间产物)氢双吡咯啉,涵盖一定范围的双吡啶饱和平(二氢,四氢,六氢),并配备了多种α-吡咯(-H,-SMe,-SPh,-Br,-Me,-CO 2个已经制备了R,二氧杂硼烷基)和α-吡咯啉(甲基,甲酰基,二甲氧基甲基,氧代,甲氧基,甲基,亚基甲基,乙氧基羰基乙烯基,双乙烯基)取代基,并在细菌绿素的定向合成中进行了研究。这些路线(受定向生成二氢卟的启发)依赖于两种氢二吡咯啉的缩合反应
  • Regioselective β-pyrrolic electrophilic substitution of hydrodipyrrin–dialkylboron complexes facilitates access to synthetic models for chlorophyll f

    Substituents in ring A of chlorophylls can exert profound effects on spectral properties. A de novo route to synthetic chlorins employs a tetrahydrodipyrrin reactant containing pyrrole and pyrroline rings. Complexation of the tetrahydrodipyrrin with a dialkylboron motif caused electrophilic substitution (bromination, formylation) to proceed predominantly at the β7- rather than α-position of the pyrrole ring, whereas an analogous dihydrodipyrrin underwent substitution equally at the 7- and 8-positions. The fully unsaturated dipyrrin–difluoroboron complex is known to undergo electrophilic substitution at the 8-position. The 7-position of the hydrodipyrrin ultimately gives rise to substituents at the chlorin 2-position (ring A), which heretofore has been little accessed. The position of substitution was confirmed by four single-crystal X-ray structures. Two isomeric formylchlorins were prepared by Pd-mediated carbonylation of the corresponding bromochlorins. Access to a 2-formylchlorin relied on bromination of the tetrahydrodipyrrin–dibutylboron complex, whereas a 3-formylchlorin was prepared by installation of the bromo group in the earliest precursor, pyrrole-2-carboxaldehyde. The two formylchlorins differ in absorption spectral properties: the Qy absorption maximum is 654 or 664 nm for the 2- or 3-formylchlorin, respectively. The synthetic formylchlorins provide initial models for understanding the strong red absorption of native 2- or 3-formylchlorophylls (f and d).
    叶绿素A环中的取代基可以对光谱特性产生深远的影响。一种合成叶绿素的新方法采用了含有吡咯吡咯啉环的四氢二吡咯反应物。四氢二吡咯与二烷基基团的络合使得电亲核取代(化、甲酰化)主要发生在吡咯环的β7位,而非α位,而一个类似的二氢二吡咯则在7位和8位的取代反应是相同的。已知完全不饱和的二吡咯–二络合物在8位进行电亲核取代。氢二吡咯的7位最终产生在叶绿素2位(A环)的取代基,而这一位置此前未被广泛研究。取代位置通过四个单晶X射线结构得到了证实。通过介导的羰基化反应制备了两种异构甲酰氯素。获得2-甲酰氯素依赖于对四氢二吡咯二丁基硼络合物的化,而3-甲酰氯素则是通过在最早的前体吡咯-2-甲醛中引入基来制备的。这两种甲酰氯素在吸收光谱特性上有所不同:对于2-或3-甲酰氯素,Qy吸收最大值分别为654或664 nm。合成的甲酰氯素为理解天然2-或3-甲酰叶绿素(f和d)的强红光吸收提供了初步模型。

    This chemical space remains largely unexplored due to a lack of reliable synthetic strategies. We now report the preparation and characterization of Co(II)- and Ni(II)-metalated TDC derivatives ([Co-TDC]+ and [Ni-TDC]+, respectively) with a combination of crystallographic, electrochemical, computational, and spectroscopic techniques. [Ni-TDC]+ was found to undergo primarily ligand-centered electrochemical
    单阴离子四吡咯大环B,C-四脱氢可林 (TDC) 在化学上位于 corroles 和 corrins 之间。由于缺乏可靠的合成策略,这个化学空间在很大程度上仍未被探索。我们现在报告结合晶体学、电化学、计算和光谱技术。[-TDC] +发现主要经历以配体为中心的电化学还原,导致在酸存在下阴极电解下大环的氢化。瞬态吸收 (TA) 光谱表明[Ni-TDC] +和双电子还原的[Ni-TDC] -具有长寿命的激发态,而单还原的[Ni-TDC]的激发态表现出皮秒动力学。Co(I) 化合物[Co-TDC]是空气稳定的,突出了 TDC 配体在稳定低价属中心方面的显着特性,这与其他四吡咯(例如通常将属稳定在较高氧化态的 corroles)不同。
