α－（アミノオキシ）カルボン酸類の製造方法
Document Type and Number:
Japanese Patent JP7370152
Kind Code:
B2
Abstract:
To provide an efficient method for producing α-(alkylidene aminooxy)carboxylic acids that are useful as a raw material for producing an aldehyde scavenger α-(aminooxy)carboxylic acid.SOLUTION: By reacting the oxime represented by the formula (1) with the α-halocarboxylic acid represented by the formula (2) in a ketone-based solvent in the presence of a base, a α-(alkylidene aminooxy)carboxylic acid represented by the formula (3) or an alkali metal salt thereof is produced. (In the formula, R1 and R2 represent a hydrogen atom or an alkyl group, R3 represents an alkyl group or a phenyl group, and X represents a halogen atom.).SELECTED DRAWING: None
