摘要

以脱镁叶绿酸-a(b)甲酯为起始原料,经外接环修饰和色基金属化形成不同的叶绿素降解产物,再通过Vilsmeier酰基化和Blanc羟甲基化反应,在20-位上引进了新的官能基团.以四氧化锇、硝酸铊和空气为氧化剂,对二氢卟吩周环上的活性结构进行氧化,分别在二氢卟吩周环上的3-,7-和12-位以及外接环上引进了甲酰基和甲酰甲基,合成了一系列未见报道的叶绿素类二氢卟吩醛衍生物,其化学结构均经UV,IR,1H NMR及元素分析予以证实;同时也讨论了叶绿素类二氢卟吩醛基化的反应机理,并对新化合物与牛血清白蛋白的结合作用进行了研究.

Abstract

Pyropheophorbide-a (b) methyl esters were used as starting materials to form different chlorophyll degradation products by the modification of the exocyclic ring and the metallization of the chromophore. The new functional groups were introduced at 20-position via the Vilsmeier acylation and the Blanc hydroxymethylation. The active structures of chlorin peripheries were oxidized using osmium tetroxide, thaillum nitrate and air as oxidizing agent to introduce the formyl group and the formylmethyl group at 3-, 7-or 12-postion and on the exocyclic ring, respectively. A series of unreported chlorin aldehydes related to chlorophyll were synthesized and their chemical structures were characterized by elemental analysis, UV, IR and 1H NMR spectra. The reaction mechanisms on the hydroformylation for the chlorophyllous chlorins were discussed and the interactions of new compounds with bovine serum albumins were researched.
