  • Synthesis of internally alkylated azuliporphyrins
    作者:Julian S. D. Moriones、Alissa N. Latham、Timothy D. Lash

    Examples of internally alkylated azuliporphyrins were prepared by MacDonald-type “3 + 1” condensations. 2-Methyl- and 2-ethylazulene reacted with an acetoxymethylpyrrole in the presence of an acid catalyst to give azulitripyrranes. Following cleavage of the terminal protective groups, condensation with a diformylpyrrole in the presence of hydrochloric acid and oxidation with ferric chloride afforded 21-alkylazuliporphyrins. An azulene dialdehyde similarly reacted with an [Formula: see text]-methyltripyrrane to generate a 23-methylazuliporphyrin. The products could only be isolated in protonated form and the free-base internally alkylated azuliporphyrins proved to be unstable. Nevertheless, the dications are highly diatropic and the internal alkyl group resonances were shifted upfield to beyond -3 ppm. Reaction of a 23-methylazuliporphyrin with palladium(II) acetate primarily afforded a palladium(II) complex with loss of the internal methyl substituent. However, two palladium(II) benzocarbaporphyrins were also identified that were formed by sequential oxidative ring contraction and methyl group migration. Internally alkylated azuliporphyrins provide new insights into the reactivity of the system and the results show that the introduction of alkyl substituents within porphyrinoid cavities greatly modifies the properties of these structures.

    通过 MacDonald 型 "3 + 1 "缩合反应制备了内部烷基化的偶氮二卟啉。在酸催化剂的作用下,2-甲基和 2-乙基唑烯与乙酰氧甲基吡咯发生反应,生成偶氮三吡喃。裂解末端保护基团后,在盐酸存在下与二甲吡咯缩合,并用氯化铁氧化,得到 21-烷基氮丙卟啉。偶氮烯二醛与[式中:见正文]-甲基三吡喃发生类似反应,生成 23-甲基偶氮二卟啉。这些产物只能以质子化形式分离出来,游离基内部烷基化的氮基二卟啉被证明是不稳定的。不过,这些二阳离子具有高度的二向性,内部烷基共振被上移到 -3 ppm 以上。23 甲基氮基卟啉与醋酸钯(II)反应,主要生成了失去内部甲基取代基的钯(II)络合物。不过,还发现了两种钯(II)苯并二氢卟啉,它们是通过连续的氧化缩环和甲基迁移形成的。内部烷基化的偶氮二卟啉为了解该体系的反应性提供了新的视角,研究结果表明,在卟啉空腔中引入烷基取代基会极大地改变这些结构的性质。
