Porphyrins 1ab and 2ab were successfully synthesized from cis-alpha2-bisimidazole-beta-imidazole-tail porphyrins and two newly synthesized imidazole pickets containing an aliphatic ester chain following a [2+1] approach. The four compounds possess a distal trisimidazole set, a distal carboxylic acid, and a proximal imidazole, which constitute all the key features of the coordination environment of
按照[2 + 1]方法成功地从顺-α2-双咪唑-β-咪唑-尾卟啉和两个新合成的含脂族酯链的咪唑基中成功合成了卟啉1ab和2ab。这四种化合物具有远端三咪唑组,远端羧酸和近端咪唑,它们构成细菌一氧化氮还原酶(NOR)活性位点配位环境的所有关键特征,并使它们成为最接近的合成NOR模型配体迄今为止。
