Two monosubstituted and one tetrasubstituted N-confused porphyrins (1–3) were prepared in ca. 3–5% yields using a [2 + 2] synthesis. The monosubstituted porphyrins have carbomethoxy (1) or nitro (2) substituents on one of the meso-phenyl groups, while the meso-phenyl groups of the third NCP (3) are substituted with nitro, bromo, and methyl groups in an AB2C pattern. The specific regiochemistry of the
两个单取代的和四取代的一个的N-混淆卟啉(1 - 3)在约制备 使用[2 + 2]合成,产率为3-5%。单取代的卟啉在一个内消旋苯基上具有一个碳甲氧基(1)或一个硝基(2)取代基,而第三个NCP(3)的内消旋苯基在一个AB 2中被硝基,溴和甲基取代C模式。使用1D(1 H和13 D的组合)确定每个卟啉中大环周围芳环的具体区域化学。C)和2D(gHMBC,gHSQC和ROESY)NMR光谱。CH 2 Cl 2中1 – 3的吸收光谱与N混淆的四苯基卟啉(NCTPP)相似,但具有Soret和Q谱带,与NCTPP相比,它们的消光系数向低能量转移。
