A series of macrocyclic diazadi(and tri)thiacrown etherscontaining two 5-substituent-8-hydroxyquinoline sidearms have been synthesized from the corresponding macrocyclic diazadi(and tri)thiacrown ethers. The crown ethers were obtained by reduction of the proper macrocyclic di(and tri)thiadiamides by borane-tetrahydrofuran or by sodium borohydride-boron trifluoride ethyl etherate-tetrahydrofuran.
