Quinoline crown thioethers (7) and (8) with 8-, 9-, 10-, 11-, 12-, 18-, 20-, 21- and 24-membered macrocyclic thiacrown ring were obtained by the 1,4-dithiin ring opening in 1,4-dithiinodiquinolines (1) and (2) with divalent sulfur nucleophiles followed by S-alkylation with divalent alkylating agents. Thiacrowns (7) and (8) contain two or four quinoline units.
