Synthesis of novel α-aminophosphonic acid esters (5a-n) were achieved with high yields through one-pot three component reaction process by Kabachnik-Fields reaction. It involves the reaction among amino acids/esters, substituted aromatic aldehydes and dialkyl phosphites in absolute ethanol at reflux temperature. Their structures were established by elemental analysis IR,¹H,¹³C,³¹P NMR and mass spectral data. All the title compounds were screened for their antibacterial activity. Most of the compounds exhibited moderate antimicrobial activity.

Abstract Nonenzymatic catalysis by bivalent ions of Be, Mg, Ca, Zn, Mn, Ni and Co and bioorganic phosphates of the formation of hydroxamic acids from acetate or amino acids has been studied systematically. Increased yields of hydroxamate were observed at particular combinations of reactants. The most prominent increase (ca. 15-fold) was found with acetate and Ni++, and with a combination of ATP and Be++. Among others especially ribose-5-phosphate and glucose-5-phosphate enhanced yields in the presence of most metal ions. Since no release of inorganic phosphate was observed, this effect cannot be interpreted as an evidence for intermediate transhosphorylation reactions; it may also result from simple catalytic effects of metal sugar complexes.

Ethyl-, propyl-, and benzyl-guanidine nitrates were prepared from amine nitrates and calcium cyanamide or dicyandiamide. Carboxyalkylguanidines were made by condensing the corresponding amino acids with guanidine carbonate in aqueous medium. All the guanidine nitrates, except the benzyl derivative, were converted into the corresponding nitroguanidines by treatment with concentrated sulphuric acid. Esters and metal salts of 1-(α-carboxyalkyl)-2-nitroguanidines were also prepared.
