| titleOfInvention | Method for producing N-substituted-2-amino-4-(hydroxymethylphosphinyl)-2- butenoic acid |
| abstract | Provided is an effective synthesizing method of a (Z)-N-substituted-2-amino-4-(hydroxymethylphosphinyl)-2-butenoic acid derivative. A compound expressed by a next chemical formula (1) (chemical formula 1) where R1 represents a hydrogen atom or a C1-4 alkyl group, and a compound expressed by a next chemical formula (2) (chemical formula 2) H2N-COR2 (2) where R2 represents a C1-4 alkyl group, C1-4 alkoxy group, aryl group, aryloxy group or benzyloxy group, are dehydro-condensed in the presence or absence of an acid catalyst to synthesize a (Z)-N-substituted-2-amino-4-(hydroxymethylphosphinyl)-2-butenoic acid derivative; in where an organic solvent used for the reaction is a mixed solvent of an acetic acid and a solvent selected from a group consisted of a toluene, xylene and chlorobenzene, where a mixing ratio of the acetic acid and the toher solvent is 1: 3 to 1: 5 in volume, and in which the reaction is conducted by heating under reflux. |
