The macrocyclictetraamides 11a-e and 15-hydroxy macrocyclictetraamides 23a-c were prepared in good yields by the nucleophilic reaction of the potassium salts of the bis-phenoles 10a-c with the appropriate dihalo compounds 5a-d and 15. Moreover, the acyclic diamides 7, 9, 17-21 and bis-acyclic tetraamide 22 were obtained in high yields by the reaction of the appropriate dichloro compounds with different
