METHOD FOR PRODUCING alpha-AMINOPHOSPHONIC ACID ESTER DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an α-aminophosphonic acid ester derivative capable of producing a product having high selectivity between a 1,4-addition reaction and [3+2] addition cyclization reaction.

SOLUTION: The method for producing an α-aminophosphonic acid ester derivative comprises the reaction of an iminophosphonate expressed by general formula (I) with an electron-deficient olefin. In the formula, R6is a hydrocarbon group which may have a substituent; R7is a hydrogen atom or a hydrocarbon group; R8is a hydrogen atom or a hydrocarbon group; and R9is a hydrocarbon group; wherein all R9groups may be the same or different.
