Six crownetherscontaining two coumarin (11, 13,14,16,17 and 19) or two 1-aminonaphthalene (15 and 20) fragments as sidearms and two crownethers bearing one coumarin (12 and 18) arm were synthesized by a nucleophilic substitution of the secondary macrocyclic amine function on the alkylhalide. The major products of these reactions were the diazadithiacrown etherscontaining two sidearms. In some
