• To establish an efficient synthetic route for these complex molecules.

Main Methods:

• Solid-phase synthesis on SynPhase lanterns.
• Utilizing amino alcohols and diamines as key building blocks.
• Employing S(N)2 alkylation of methanesulfonates with amines for coupling.
• Introducing N-4-nitrobenzyloxycarbonyldiamines for facile purification.

Main Results:

• Successfully synthesized a library of nine polyamine-imidazole conjugates.
• The synthetic strategy allowed for controlled assembly of the target structures.
• The use of specific protecting groups facilitated straightforward purification of the final products.

Conclusions:

• A versatile synthetic approach for polyamine-imidazole conjugates was developed.
