  Investigation of the Scope of a New Route to ABCD-Bilanes and ABCD-Porphyrins

  摘要：

  A new route to bilanes and porphyrins bearing four distinct meso substituents has been studied to elucidate the scope and gain entry to previously inaccessible compounds. The route entails (i) synthesis of a 1-bromo-19-acylbilane by acid-catalyzed condensation of a 1-acyldipyrromethane and a 9-bromodipyrromethane-1-carbinol and (ii) intramolecular cyclization of the 1-bromo-19-acylbilane in the presence of a metal salt (MgBr2, 3 mol equiv) and a non-nucleophilic base (DBU, 10 mol equiv) in a noncoordinating solvent (toluene) at 115 degrees C exposed to air to afford the corresponding magnesium(II) porphyrin. In this study, two sets of bilanes were initially prepared to explore substituent effects. In the first set, all bilanes vary only in the nature of the substituent at the 10-position. In the second set, all bilanes vary only in the nature of the substituent attached to the acyl unit (the 20-position). The substituents examined at the 10- and 20-positions include alkyl, aryl (electron-rich, electron-deficient, hindered), heteroaryl, ester, or no substituent (-H). The bilanes were obtained in 35-87% yield, and the target porphyrins in up to 60% yield. Further study of the scope focused on bilanes and porphyrins bearing three heterocyclic substituents (o-, m-, p-pyridyl) or four alkyl groups (ethyl, propyl, butyl, pentyl), in which case microwave irradiation was used for the porphyrin-forming step. Altogether, 17 bilanes and 19 porphyrins were prepared and characterized. In summary, the new route provides access to meso-substituted bilanes and porphyrins for which access is limited via other methods.

  using EtMgBr and an acid chloride has been refined. A new procedure for the preparation of unsymmetrical diacyl dipyrromethanes has been developed that involves (1) monoacylation with EtMgBr and a pyridyl benzothioate followed by (2) introduction of the second acyl unit upon reaction with EtMgBr and an acid chloride. The scope of these acylation methods has been examined by preparing multigram quantities

  带有特定取代基图案的卟啉是仿生和材料化学中至关重要的组成部分。我们已开发出避免统计反应的方法，采用最少的色谱法，并提供最多克量的区域异构纯卟啉，带有多达四个不同内消旋取代基的预先指定图案。该方法基于几克数量的二吡咯甲烷的可用性。使用EtMgBr和酰氯对二吡咯甲烷进行二酰化的方法已经完善。已经开发出一种新的制备不对称二酰基二吡咯甲烷的方法，该方法涉及（1）用EtMgBr和吡啶硫基吡啶酯单酰化，然后（2）在与EtMgBr和酰氯反应时引入第二个酰基单元。通过制备多克量的带有各种取代基的二酰基二吡咯甲烷，已经检验了这些酰化方法的范围。用NaBH（4）在甲醇THF中将二酰基二吡咯甲烷还原为相应的二吡咯甲烷-二甲醇。卟啉的形成涉及二吡咯甲烷-二甲醇和二吡咯甲烷的酸催化缩合，然后用DDQ氧化。通过检查各种反应参数（溶剂，温度，酸，浓度，时间），可以确定最佳的缩合条件。确定的条件（2.5 mM反应物在室温下含有30

  multistep synthesis which requires a 2e- + 2H+ reduction per each 1-acyldipyrromethane (4e- + 4H+ overall) followed by a 6e- + 6H+ oxidation. The analogous reaction of a 1,9-diacyldipyrromethane and a dipyrromethane also gives the palladium porphyrin. Seven palladium porphyrins have been prepared in yields of 25−57%. The direct route also can be used with Cu(OAc)2·H2O to give the copper porphyrin albeit

  钯卟啉在生物学和材料化学中是有价值的光敏剂和发光剂。描述了一种新的方法，其中通过一个烧瓶反应将1-酰基吡咯甲烷转化为反式-A 2 B 2卟啉的钯螯合物。该反应需要在回流的含KOH（5-10摩尔当量）和Pd（CH 3 CN）2 Cl 2的乙醇中使1-酰基吡咯甲烷自缩合。（0.6摩尔当量）暴露在空气中。这种直接生成钯卟啉的途径比传统合成的四个步骤更方便：（1）还原1-酰基吡咯甲烷；（2）酸催化缩合；（3）卟啉原中间体的氧化；（4）金属插入。新的合成需要既不产酸也不DDQ并正式需要仅一个2E - + 2H +氧化整体相对于传统的多步合成，其需要一个图2e - + 2H +每每个1 acyldipyrromethane减少（图4e - + 4H +后跟一个整体）图6e - + 6H +氧化。1,9-二酰基二吡咯甲烷和二吡咯甲烷的类似反应也产生了钯卟啉。制备了7种钯卟啉，收率25-57％。该直接途径也可以与Cu（OAc）2
