以脱镁叶绿酸-a甲酯(MPa)为起始原料, 经化学结构修饰和中心氮原子金属化后, 与三氯氧磷/3-N,N-二甲基氨基丙烯醛(3-DMA)或者N,N-二甲基甲酰胺进行Vilsmerier反应, 在二氢卟吩周环上区域选择性地引进甲酰基或者甲酰乙烯基; 用硝酸铊对MPa衍生物实施氧化, 将3-位乙烯基顺利地转化为甲酰甲基; 利用3-位乙烯基和E-环酮基的化学反应活性, 在大环上引进羟烷氧基或者羟烷氨基结构, 然后选用高钌酸四丙基铵(TPAP)和N-甲基吗啉-N-氧化物混合氧化剂, 分别将其羟基氧化成甲酰基. 新合成的连有酰基结构的二氢卟吩衍生物的化学结构均经UV, IR, 1H NMR及元素分析得以证实.

Methyl pheophorbide-a (MPa) was used as starting material and converted to Ni(II) complexes by modifying for chemical structures and metallizing with Ni(acac)2. Their Vilsmerier reactions with phosphoryl chloride and 3-(dimethyl- amino)-acrolein or N,N-dimethylformamide were performed regioselectively to introduce formyl or formylvinyl group on the periphery of chlorin. The formylmethyl group also was established by oxidation reaction of the C(3)-vinyl group with thallium nitrate. The hydroxyalkyloxyl or hydroxyalkylamino group on the macrocycle was constructed based on the chemical activities of the vinyl group at 3-position and ketone group in E-ring and subsequently the hydroxyl group was oxidized with the conbination of tetrapropylammonium perruthenate (TPAP) and N-methylmorpholine N-oxide to the corresponding formyl group, respectively. The structures of all the new chlorins containing acyl structure were characterized by UV, IR, 1H NMR spectra and elemental analysis.
