Abstract

An effective procedure for the preparation of imines based on 4-methyl-4-diphenylphosphorylpentan-2-one, aminoacetic, aminopropionic, and aminobutyric acids with yields of 90–95% was developed. Reaction of dimephosphone (4-methyl-4-dimethoxyphosphorilpentan-2-one) with potassium salts of these amino acids led to methylation of the carboxy group of the amino acid to form potassium salt of 2-methyl-4-oxopentylphosphonic acid methyl ester.
