چکیده
|
In this paper, a new and convenient method is introduced for the oxidation of a variety ofhantzsch 1, 4-dihydropyridine derivatives to their corresponding pyridine compounds using guanidiniumnitrate and silica sulfuric acid. the reactions were carried out in dichloromethane at room temperatureand the products were isolated at high to excellent yields.
