Enantioselective Desymmetrization of 1,4-Dihydropyridines by Oxidative NHC Catalysis

, 2019
The unprecedented desymmetrization of prochiral dialdehydes catalyzed by N-heterocyclic carbenes under oxidative conditions was applied to the highly enantioselective synthesis of 1,4-dihydropyridines (DHPs) starting from 3,5-dicarbaldehyde substrates ...

Facile, Regioselective [4 + 2] Cycloaddition Involving 1-Aryl-4-phenyl-1-azadienes and Allenic Esters:  An Efficient Route to Novel Substituted 1-Aryl-4-phenyl-1,4-dihydropyridines

, 2016
1-Aryl-4-phenyl-1-azadienes undergo facile, regioselective [4 + 2] cycloaddition to the C2,C3 π-bond of allenic esters in refluxing benzene, and the formed adducts undergo a 1,3-H shift to afford novel 2-alkyl-1-aryl-3-ethoxycarbonyl-4-phenyl-1,4 ...

Synthesis of 1,4-Dihydropyridines Bearing a Carbamate Moiety on the 4-Position

Journal of Chemistry, 2013
A good range of 1,4-dihydropyridines bearing a carbamate moiety on the 4-position were synthesized from the primary reaction of different hydroxyaldehydes with phenyl isocyanates and the subsequent reaction of the obtained carbamates with methyl ...

Hantzsch reaction: Recent advances in Hantzsch 1,4-dihydropyridines

, 2008
95-111Hantzsch reaction seems to be one of the earliest procedures for the production of pyridines. Later on, Hantzsch 1,4- dihydropyridines, which mimic NADH reduction process in vitro, have shown promising biological activities.
