The macrocyclictetraamides 8a-e were obtained in good yields by bis-alkylation of the potassium salts of the appropriate bisphenols 7a-c with the dihalo compounds 2a,b. Similarly, macrocyclictetraamides with pendant hydroxy group 18a,b were prepared by the nucleophilic reaction of the potassium salts of 7a,b with the dihalo compound 10. Acylation of 18a,b with chloroacetyl chloride gave the corresponding

RCM of the appropriate bis-allyloxyacetanilides and bis-o-allyloxyphenoxyacetanilides led to an efficient synthetic approach to the corresponding macrocylic polyoxadiamides with 20- to 32-membered ring sizes in good to excellent yields using Grubbs' catalyst.
