Conditions have been identified for the efficientUllmann macrocyclization of phenol and imidazole nucleophiles with aryl iodides at high reaction concentrations of up to 100 mM and using 5–10 mol % loading of an inexpensive coppercatalyst. A range of substitution patterns and ring sizes are tolerated, and the method has been exemplified by the synthesis of a set of druglike macrocycles.
