以焦脱镁叶绿酸-a甲酯为原料,通过E-环羰基分别与苯肼和氨基酸反应合成了焦脱镁叶绿酸-a甲酯苯腙和焦脱镁叶绿酸-a氨基酸席夫碱.苯腙的最大吸收波长显著红移.席夫碱最大吸收波长稍有蓝移,而其水溶性明显增大.所有新化合物的结构经1H NMR,MS或元素分析所证实.
Methyl pyropheophorbide-a was used as starting material for the synthesis of phenylhydrazone and amino acid Schiff base by reactions of carbonyl group at 131-position. The maximum absorption wavelength of phenylhydrazone caused a red shift. The water-solubility of Schiff base was incremented, and the maximum absorption wavelength shifted hypsochromically. The structures of all these compounds were characterized by 1H NMR, MS and elemental analysis.
