Abstract
Abstract Methyl esters of N-(O,O-diethylphosphonobenzyl-)-2-amino-3-aryl-propanoic acid were synthesized by the addition of diethylphosphite to Schiff bases of 2-amino carboxylic acids (L-phenyl-alanine and L-tyrosine). The compounds were obtained as a mixture of [sgrave]-diastereoisomers and the structures were confirmed by spectral methods.
