  Rational Synthesis of Trans-Substituted Porphyrin Building Blocks Containing One Sulfur or Oxygen Atom in Place of Nitrogen at a Designated Site

  摘要：

  The use of heteroatom-substituted porphyrins in bioorganic and materials chemistry requires the ability to position a variety of substituents in a controlled manner about the porphyrin periphery. We describe a rational route to trans-AB(2)C-type porphyrins bearing one oxygen atom (N3O) or one sulfur atom (NBS) in a designated location in the porphyrin core. The synthesis involved four stages: (1) Acid-catalyzed condensation of a furyl- or thienylcarbinol in excess pyrrole afforded the aryl-substituted furyl- or thienylpyrromethane in high yield. (2) Treatment of the furyl- or thienylpyrromethane with an acid chloride catalyzed by SnCl4 or AlCl3 afforded the corresponding diketo product. (3) Reduction with NaBH4 in alcoholic solvents gave the furyl- or thienylpyrromethanediols. (4) Reaction of a furylpyrromethanediol, thienylpyrromethanediol, or dipyrromethanediol with a dipyrromethane in a one-flask process of condensation followed by oxidation gave the corresponding porphyrin. Reaction conditions previously identified to minimize scrambling in a dipyrromethane-aldehyde condensation were found to be effective in this application. Thus, reaction with 10 mM reactants in acetonitrile at 0 degrees C containing BF3 . Et2O and NH4Cl followed by oxidation with DDQ resulted in the desired porphyrin(10-20% yields) without acidolysis. In this manner, N3O-, N3S-, or Na-porphyrins bearing 5-(p-iodophenyl), 15-[4-(2-(trimethylsilyl)ethynyl)phenyl], and 10,20-di-p-tolyl groups have been made. This set of trans-substituted porphyrin building blacks is expected to be useful in the synthesis of biomimetic energy transduction systems.

  achieved by reaction of a porphyrin pentamer + porphyrin monomer or the joining of two porphyrin trimers. In the presence of a tripyridyl template, the yields of the 5 + 1 and 3 + 3 reactions ranged from 10 to 13%. The 5 + 1 reaction in the absence of the template proceeded in 3.5% yield, thereby establishing the structure-directed contribution to cyclic hexamer formation. The 3 + 3 route relied on successive

  卟啉的两个新的环状六聚体阵列已经以合理，会聚的方式制备。每个环状六聚体中的卟啉通过联苯乙炔连接剂连接，提供直径约35 A的轮状阵列。一个阵列由5个锌（Zn）卟啉和1个游离碱（Fb）卟啉（环-Zn（5 ）FbU），而另一个则由两个锌卟啉和一个Fb卟啉的交替序列组成（cyclo-Zn（2）FbZn（2）FbU）。先前的合成采用单烧瓶模板指导的方法，并得到交替的Zn和Fb卟啉或所有Zn卟啉。更多样化的金属化图案对于操纵阵列中激发态能量的流动具有吸引力。每个阵列的合理合成采用了三个Pd介导的偶联反应，以及四个带有二乙炔基，二碘，溴/碘或碘/乙炔基的四芳基卟啉构件。通过卟啉五聚体+卟啉单体的反应或两个卟啉三聚体的连接来实现产生环状六聚体的最终闭环。在存在三吡啶基模板的情况下，5 +1和3 + 3反应的产率为10％至13％。在没有模板的情况下的5 +1反应以3.5％的产率进行，从而确定了结构对环状六聚体形成的贡献。3
