Procedure

Monoquaternary spermine containing hydrophilic head-group was prepared in a similar way to compound 3. Briefly, TriBoc-Spermine was reacted with excess of 1-azido-3-iodo-propane in the presence of excess TBA. The resulting quaternarized derivative was hydrogenised under (Pd—C) and Boc protecting group were removed using gaseous HCl in dry methanol.
