Macrocyclizations for medicinal chemistry: Synthesis of druglike macrocycles by high-concentration ullmann coupling
Conditions have been identified for the efficient Ullmann 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 copper catalyst. 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.
