Abstract
PURPOSE: To obtain β-hydroxyamino acid in high yield, without side reactions, and high steric selectivity, by the reaction of a moderately reactive α-isocyanoacetic acid dialkylamide with an aldehyde or a ketone, followed by hydrolysis.
CONSTITUTION: α-Isocyanoacetic acid dialklamide of formula I (R3, R4=alkyl) obtained by the reaction of α-isocyanoacetic acid ester with dialkylamine, e.g. α-isocyanoacetic acid dimethylamide, is made to react with an aldehyde or a ketone of formula II (R1=H, COOH, alkyl, etc,; R2=H, alkyl) in the presence of a base, e.g. NaOH, to prepare 5-substituted or unsubstituted-2-oxazoline-4-carboxylic acid dialkylamide. The compound obtained is hydrolyzed to prepare β-hydroxyamino acid of formula IV.
