Synthesis of neoglycolipids for the development of non-viral gene delivery systems

Synthesis of lipid conjugates with galactose as a targeting ligand intended for the development of non-viral systems for the targeted delivery of nucleic acids into hepatocytes is described. 3,4-Diethoxycyclobut-3-ene-1,2-dione (diethyl squarate) was used to bind the galactose moiety to the lipid component.
