Hantzsch dihydropyridine synthesis
-
This study reports the design, synthesis, and calcium channel modulatory activity evaluation of a series of 14 novel fused 1,4-dihydropyridine derivatives. The molecular design of the compounds was based on modifications of nifedipine, which is a calcium channel blocker. The compounds were achieved by one-pot microwave-assisted reaction of 4,4-dimethyl-1,3-cyclohexanedione, 5-chlorosalicylaldehyde/3,5-dichlorosalicylaldehyde, an appropriate alkyl acetoacetate, and ammonium acetate in ethanol according to a modified Hantzsch reaction.

In this study, a green and practical approach towards Hantzsch dihydropyridine synthesis of acridine-1,8-diones is introduced. Via the mentioned protocol, the one-pot condensation reaction of structurally diverse aromatic aldehydes, dimedone and NH4OAc was promoted by microwave radiation at solvent and catalyst-free conditions.
