An unusual greater reactivity of phosphonous propionic acids was found in comparison with phosphonous propionic esters in carbamate version of Kabachnik–Fields reaction. Compounds of tricoordinated phosphorus generated in situ during the amidoalkylation of hydrophosphorylic compounds in acetyl chloride/acetic anhydride mixture were found by 31P NMR analysis. A hypothesis is proposed about the generation

The present invention relates generally to amino acid derivatives and to methods of making the same. In particular, the invention relates to compounds bearing a stereochemical identity, that is, the same stereochemistry, with the chiral α-carbon of D-α-amino acids and their use in methods of therapy, including the treatment of inflammatory diseases, and to compositions and enantiomeric mixtures containing them.

A series of substituted phosphonate derivatives were designed and synthesized in order to study the ability of these compounds to inhibit the neuropeptidase N-acetylated alpha-linked acidic dipeptidase (NAALADase). The molecules were shown to act as inhibitors of the enzyme, with the most potent (compound 3) having a K-i of 0.275 nM. The potency of this compound is more than 1000 times greater than that of previously reported inhibitors of the enzyme. NAALADase is responsible for the catabolism of the abundant neuropeptide N-acetyl-L-aspartylglutamate (NAAG) into N-acetylaspartate and glutamate. NAAG has been proposed to be a neurotransmitter at a subpopulation of glutamate receptors; alternatively, NAAG has been suggested to act as a storage form of synaptic glutamate. As a result, inhibition of NAALADase may show utility as a therapeutic intervention in diseases in which altered levels of glutamate are thought to be involved.
