Abstract

PURPOSE: To obtain the title compound useful as herbicides, by reacting a β-halogenoethyl ester of methyl-β-halogenoethyl-phosphinic acid with an amino-carboxylic ethyl ester in the presence of an alkali in an organic solvent.
CONSTITUTION: A β-halogenoethyl ester of methyl-β-halogenoethyl-phosphinic acid of formula I: (X is halogen) is reacted with a compound of formula II: (R is H, alkyl, or aryl group; R1 is alkoxycarbonyl, cyano, or acetonitrile group) in the presence of an alkali, e.g. a metal alcoholate or hydroxide, in an organic solvent, e.g. THF, at a low temperature to give a reaction product, which is hydrolyzed to form a γ-amino-α-carboxypropyl-methylphosphinic acid or its salt.
EFFECT: High yield and intermediate preparation in one step.
