Title:

PROCESS FOR PRODUCING AMINOPHOSPHONIC ACID DERIVATIVE

Document Type and Number:

WIPO Patent Application WO2005085262

Kind Code:

B1

Abstract:

[PROBLEMS] To provide a reaction system in which enantioselective asymmetric nucleophilic addition to an alpha-iminophosphonic ester is efficiently catalyzed. [MEANS FOR SOLVING PROBLEMS] An alpha-iminophosphonic ester is subjected to asymmetric addition reaction with a nucleophilic agent (e.g., a silylenol ether) in the presence of a chiral copper catalyst (JP 2003-260363 A) to produce an optically active alpha-amino-gamma-oxophosphonic acid derivative.
