(hydroxymethyl, formyl, ester) directly attached to the macrocycle afford a compact architecture that is attractive for diverse applications. Routes to 9 porphyrins bearing such groups in distinct architectures (A(4)-, trans-A(2)-, trans-A(2)B(2)-, trans-AB- and trans-AB(2)C-porphyrins) have been explored (A = hydroxymethyl), including porphyrins bearing two one-carbon units in different oxidation states
带有直接连接到大环上的一碳含氧取代基(羟甲基、甲酰基、酯)的卟啉提供了一种紧凑的结构,对各种应用都很有吸引力。在不同结构(A(4)-、反-A(2)-、反-A(2)B(2)-、反-AB-和反-AB(2)C-)中9个卟啉的路线卟啉)已被探索(A = 羟甲基),包括带有两个不同氧化态(羟甲基/酯、甲酰/酯)的单碳单元的卟啉。羟甲基是通过 TBDMS 保护的二吡咯甲烷前体引入的。
