Abstract
An approach to the stereoselective oxidation of 5,6-bis(hydroxymethyl)-2,2,8-trimethyl-4H-[1,3]dioxino[4,5-c]pyridine and 5,6-bis(hydroxymethyl)-2,4-dimethyl-3-hydroxypyridine with manganese dioxide has been developed, intermediates and by-products have been isolated. In solutions, pyridoxine derivatives containing a carbaldehyde group exist in cyclic hemiacetal and open hydroxyaldehyde forms.
期刊介绍:
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
