  Boron-Complexation Strategy for Use with 1-Acyldipyrromethanes

  摘要：

  1-Acyldipyrromethanes are important precursors in rational syntheses of diverse porphyrinic compounds. 1-Acyldipyrromethanes are difficult to purify, typically streaking upon chromatography and giving amorphous powders upon attempted crystallization. A solution to this problem has been achieved by reacting the 1-acyldipyrromethane with a dialkylboron triflate (e.g., Bu2B-OTf or 9-BBN-OTf) to give the corresponding B,B-dialkyl-B-(1-acyldipyrromethane)boron(III) complex. The reaction is selective for a 1-acyldipyrromethane in the presence of a dipyrromethane. The 1-acyldipyrromethane-boron complexes are stable to routine handling, are soluble in common organic solvents, are hydrophobic, crystallize readily, and chromatograph without streaking. The 1-acyldipyrromethane can be liberated in high yield from the boron complex upon treatment with 1-pentanol. Alternatively, the 1-acyldipyrromethane-boron complex can be used in the formation of a trans-A(2)B(2)-porphyrin. In summary, the boron-complexation strategy has broad scope and greatly facilitates the isolation of 1-acyldipyrromethanes.

  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

  1,9-Diacyldipyrromethanes are important precursors to porphyrins, yet synthetic access remains limited owing to (1) poor conversion in the 9-acylation of 1-acyldipyrromethanes and (2) handling difficulties because acy1dipyrromethanes typically streak upon chromatography and give amorphous powders upon attempted crystallization. A reliable means for converting a dipyrromethane to a 1-acyldipyrromethane-dialkylboron complex was recently developed, where the dialkylboron (BR2) unit renders the complex hydrophobic and thereby facilitates isolation. Herein a refined preparation of 1,9-diacyldipyrromethanes is presented that employs the 1-acyldipyrromethane-BR2 complex as a substrate for 9-acylation. The dialkylboron unit provides protection for the alpha-acylpyrrole unit. 9-Acylation requires formation of the pyrrolyl-MgBr reagent and the presence of 1 equiv of a nonnucleophilic base to quench the proton liberated upon alpha-acylation. Reaction of the 1-acyldipyrromethane-BR2 complex (1 equiv) with mesitylmagnesium. bromide (2 equiv) followed by the addition of an acylating agent (S-2-pyridyl thioate or acid chloride, 1.1 equiv) gives the corresponding 1,9-diacyldipyrromethane-BR2 complex. The acylation method afforded 1,9-diacyldipyrromethaneBR(2) complexes with limited or no chromatography in yields of 64-92%. The 1,9-diacyldipyrromethane-BR2 complexes are stable to routine handling, are readily soluble in common organic solvents, crystallize readily, and can now be prepared in multigram quantities through use of stoichiometric quantities of reagents.
