have been synthesized directly from the corresponding unprotected sugars and dithiocarbamate salts in good yields by using 2-chloro-1,3-dimethylimidazolinium chloride (DMC) as condensing agent in aqueous media. The three-component one-pot synthesis of GDTCs starting from unprotected sugars, carbon disulfide, and secondary amines has also been successfully demonstrated. This is the first report on the
