The oxidation of 2 by I₂-KIO₃-AcOH-H₂O system has been studied. Instead of 3, the cisglycol(C₂₂S, C₂₃S) was obtained in yield of 78.5%, as the major product obtained in the oxidation of 2 by osmium tetroxide. The possible mechanism,of the oxidation reaction was discussed.
- potassium iodate,
- oxidation,
- brassinolide
