运用密度泛函(DFT)理论,在B3LYP/6-31G水平下,系统研究了ATMP,EDTMP,HDTMP,GDMP,MADMP这5种甲叉膦酸类阻垢缓蚀剂分子结构与阻垢性能之间的构效关系。

In order to improve the therapeutic efficacy of retinoid carboxylic acids,a symmetric type of methylene diester was designed and synthesized by coupling two molecular retinoid carboxylic acids with one molecular dibromomethane.

为了改善类维生素A酸的疗效,利用两分子类维生素A酸与一分子二溴甲烷偶联,设计合成了具有结构对称性的4种类维生素A酸甲叉二酯,即全反式维A酸甲叉二酯、异维A酸甲叉二酯、阿维A酸甲叉二酯、阿达帕林甲叉二酯,并以1H NMR,MS对它们进行了结构确证。
