Abstract

A process for preparing L - (-) - erythro-alpha, beta-dihydroxybutyraldehyde, characterized by being treated with a soft oxidizing agent, such as lead tetraacetate, at a temperature of 10 to 25º C, L - (+) - Rhamnosium dissolved in a diluted lower aliphatic organic acid (preferably acetic acid) and once the reagent is removed by oxalic acid, the reaction mixture is subjected to treatment with a dilute inorganic acid (such as sulfuric acid or hydrochloric acid) and isolated and purified, in a known manner, L - (-) - erythro-alpha, beta-dihydroxybutyraldehyde.
