Diastereoselective synthesis of racemic and enantiopure 3-aryl-5-ethyl-1,4,2-oxazaphosphorines, including those bearing phenolic hydroxyl groups in the exocyclic aromatic fragment, was implemented by the reaction of imines derived from (+/-)- and (R)-(-)-2-aminobutan-1-ol and (hydroxy)benzaldehydes with triethyl phosphite and trifluoroacetic acid, followed by the one-pot dealkylation of the intermediate esters.

New alpha-amino phosphonates containing different alkyl and aryl substituents at the alpha-carbon atom were synthesized in high yields by the Kabachnik-Fields and Pudovik reactions. These compounds were studied as carriers of several alpha-hydroxy carboxylic and dicarboxylic acids through liquid impregnated membranes. These alpha-amino phosphonates studied are capable of molecular recognition of oxalic acid among structurally similar alpha-hydroxy carboxylic and dicarboxylic acids. The efficiency and selectivity of mass transfer of oxalic acid increase with an increase in the lipophilicity of the alpha-amino phosphonate.
