Abstract: 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 compounds like 2-aminoethanol, ethyleneglycol, ethylenediamine, 2-aminoethanethiol, 2-hydroxyethanethiol, monopotassium dihydrogenphosphate to obtain the title compounds 6-11 and 12-17. The title compounds showed promising antimicrobial, antioxidant activities and was greatly influenced by the presence of different bioactive groups.
