Abstrakt:	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. [ABSTRACT FROM AUTHOR]
