Abstract: Four new 2-amino-5,7-dimethyl-1,8-naphthyridine derivatives (1–4) possessing urea, amide-imidazolium salt, amide-azide, or amide-triazole moieties were synthesized in good to excellent yields by derivatization of 2-amino-5,7-dimethyl-1,8-naphthyridine. We examined their anion recognition abilities towards different anions such as… read more here.
