A series of novel phosphorylated derivatives of galanthamine 6–11 and 12–17 were synthesized in two step process with high yields. In the first step galanthamine 1 was reacted with bis (2-chloroethyl) phosphoramidic dichloride 2/4-nitrophenyl phosphorodichloridate 3 in presence of triethylamine (TEA) in dry tetrahydrofuran (THF) yielded the intermediates 4/5. They were further reacted with various
分两步合成了高产率的一系列新颖的加兰他敏6-11和12-17磷酸化衍生物。在第一步骤中雪花胺1与双(2-氯乙基)磷酰胺二氯化物反应2 /4-硝基苯基磷酸酯3中在干燥的四氢呋喃(THF)的三乙胺(TEA)的存在下,得到中间体4/5。它们进一步与各种化合物如2-氨基乙醇,乙二醇,乙二胺,2-氨基乙硫醇,2-羟基乙硫醇,磷酸二氢钾反应,得到标题化合物6-11和12-17。标题化合物显示出令人鼓舞的抗微生物,抗氧化活性,并受到不同生物活性基团的存在的极大影响。
