| titleOfInvention | Process for production of optically active aminophosphinylbutanoic acids |
| abstract | A process for producing an optically active aminophosphinylbutanoic acid represented by the general formula (2), comprising the step for conducting the asymmetric hydrogenation of a compound represented by the general formula (1) in the presence of a ruthenium-(optically active phosphine) complex. (1) wherein R1 represents an alkyl group having 1 to 4 carbon atoms; R2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R3 represents an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, an aryl group, an aryloxy group or a benzyloxy group; and R4 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. (2) wherein R1 represents an alkyl group having 1 to 4 carbon atoms; R2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R3 represents an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, an aryl group, an aryloxy group or a benzyloxy group; R4 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; and "*" means that a carbon having this symbol is an asymmetric carbon atom. The process enables to produce a compound useful as a herbicide such as L-AHPB, at good efficiency and at high asymmetric yield. |
