Copper Catalyzed Regioselective and Stereospecific Aziridine Opening with Pyridyl Grignard Nucleophiles
Organic Letters(2022)
摘要
Copper catalyzed regioselective and stereospecific coupling between aziridines and in situ generated pyridine Grignard reagents is reported. This method provides β-pyridylethylamines with diverse structures and functionalities from aziridines and iodopyridines. β-Pyridylethylamines are potential scaffolds for the synthesis of biologically active compounds often found in pharmaceuticals. The synthesis of challenging chiral dihydroazaindoles was also achieved through mild one-pot reaction conditions via aziridine opening followed by nucleophilic cyclization.
