Abstract The anodic oxidation of (±)-1, 2-O-isopropylideneglycerol at a silver/silver oxide electrode with a controlled potential of+ 0.9 V vs. SCE in 2.5 N sodium hydroxide affords sodium (±)-2, 3-O-isopropylideneglycerate in a yield of 75%. Treatment of this salt with dimethyl sulfate and potassium carbonate in boiling acetone leads to methyl (±)-2, 3-O- isopropylideneglycerate in a yield of 81%.
