A se­ries of new organic Schiff bases were synthesized starting from diacetone-D-glucose following the general protocol of con­densation between amine and aldehyde, either both having sugar moiety (condensation of amino sugar with aldehyde sugar), and/or at least one component having sugar moiety. All the compounds that we synthesised were characterised by NMR, FT­IR, and mass spectral studies. One of the organic Schiff base SSB-4 which was synthesized by condensation of amino sugar with aldehyde sugar, expected to be a good precursor for the synthesis of macrocycle and might also show some biological activity.
