Abstract
Provided is a method for producing an optically active ceramide by an N acylation (amidation) reaction of an optically active aminodiol wherein a crude ceramide produced therein is purified by an industrially advantageous process. Namely provided is a method for producing a high purity ceramide that has high diastereo purity with high yield. A high purity ceramide is produced by: a step wherein a ceramide represented by general formula (1) is produced by reacting an aminodiol with an alkyl ester having 1 5 carbon atoms of an aliphatic carboxylic acid having 12 24 carbon atoms said aliphatic carboxylic acid optionally having a hydroxyl group in a hydrocarbon solvent having 5 10 carbon atoms; and a step wherein an alcohol having 1 3 carbon atoms is added into the reaction mixture obtained in the preceding step thereby causing crystals to precipitate. (In the formula R represents an alkyl group which has 13 17 carbon atoms and optionally has a carbon carbon unsaturated bond; R represents an alkyl group which has 11 23 carbon atoms and optionally has a hydroxyl group; and * represents an optically active state.)
