Abstract

The autoxidation mechanism for L-ascorbic acid (ASA)-related compounds such as D-arabo-ascorbic acid (=erythorbic acid; ERA) and triose reductone (TR) in methanol without metal ion catalysis was studied. The oxidation reaction of these ASA-related compounds seems to proceed via the C(2) oxygen adduct of ERA (or TR) by a similar reaction mechanism to that of ASA.
