Abstract It has been established that oxidation of a mixture of 1-methyl-4-phenyl-1, 2, 3, 6- tetrahydropyridine and dicyanomethane or formaldehyde with manganese dioxide gives 3- hydroxymethyl-1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine, the structure of which was confirmed by X-ray structural analysis. Some oxidative conversions by potassium permanganate of the product formed and its esters have been studied. These included ...
