An efficient method for the oxidation of hantzsch 1,4-dihydropyridines to their corresponding pyridine derivatives under mild and heterogeneous conditions

Article abstract of DOI:10.1080/00397910008087352

A combination of oxalic acid dihydrate and sodium nitrite in the presence of wet SiO₂ was used as an effective oxidizing agent for the oxidation of dihydropyridines to their corresponding pyridine derivatives at room temperature with excellent
