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.

The synthesis and pharmacological evaluation of a series of 2-[(arylsulfonyl)methyl]-4-aryl-5-cyano-1,4-dihydropyridine-3-carboxylic acid esters and analogues are described. These compounds possess a unique profile namely, calcium channel blocking and positive inotropic activities in vitro. Compound 54 was selected as the best compound in the series and was studied in detail. The synthesis and biological
