9-Phenyl-10-methylacridinium: A Highly Efficient and Reusable Organocatalyst for Mild Aromatization of 1,4-Dihydropyridines by Molecular Oxygen
摘要:
The mild, efficient, and general aerobic aromatization of Hantzsch 1,4-dihydropyridines was realized at room temperature with 5 mol % of 9-phenyl-10-methylacridinium perchlorate as the photocatalyst, which could be easily recovered and reused.
