以叶绿素降解产物脱镁叶绿酸-a甲酯为起始原料,利用其二氢卟吩大环上的活性反应区域,沿着N21-N23轴向进行官能团修饰,对五元外接E-环也实施了结构改造,在周环上分别引进了能与大环色基形成不同共轭程度的芳香性取代基团,完成了12个未见报道的叶绿素类二氢卟吩衍生物的合成,其化学结构均经UV,IR,1H NMR和质谱及元素分析予以证实,同时也讨论了芳基的引进对二氢卟吩的理化性质所产生的各种影响.

Pyropheophorbide-a methyl ester, as a degraded product from chlorophyll-a, was used as a starting material, and the modifications for functional group along N21-N23-axis and reconstructions for five-membered exocyclic E-ring were completed to introduce different aromatic groups which could conjugated with macrocyclic chromophore at various degrees on the periphery. The syntheses of 12 unreported chlorins related to chlorophyll were accomplished and their chemical structures were characterized by elemental analysis, UV, IR, MS and 1H NMR spectra. The different effects on the physical and chemical properties of chlorophyllous chlorins by introduction of aromatic groups were discussed.

Key words: chlorophyll-a, chlorin, chemical modification, substitution of aromatic group, synthesis
