  1. 对其羟基进行烷基化和酰基化,合成出N取代红紫素18酰亚胺衍生物。

    The alkylation and acylation for hydroxyl group linked with nitrogen were accomplished to give N alkoxy and N acyloxy purpurin 18 imides , respectively .

  2. 所得氧化产物进而和盐酸羟胺反应,经胺解开环和再缩合成环构成N羟基红紫素18酰亚胺衍生物;

    The oxidized products were reacted with hydroxylamine hydrochloride to generate purpurin 18 imide by ammonolysis and recondensation .

  3. 红紫素-18酰亚胺衍生物的合成及其可见光谱的研究

    Synthesis of Derivatives of Purpurin-18 Imide and Research on the Visible Spectra

  4. 合成的一系列红紫素-18酰亚胺衍生物具有长波长的紫外吸收。

    A series of novel purpurin-18 imide derivatives with long absorption wavelength were synthesized through Wittig reaction of methyl pheophorbide-a.
