Synthesis of Symmetrical and Unsymmetrical N,N′-Diaryl Guanidines via Copper/N-Methylglycine-Catalyzed Arylation of Guanidine Nitrate
摘要:
CuI/N-methylglycine-catalyzed coupling reaction of guanidine nitrate with both aryl iodides and bromides takes place at 70-100 degrees C, affording symmetrical N,N'-diaryl guanidines with good to excellent yields. Unsymmetrical N,N'-diaryl guanidines can be assembled via monoarylation of guanidine nitrate with aryl iodides bearing a strong electron-withdrawing group and subsequent coupling with another aryl iodide.
