Abstract: Esters of glyoxylic acids are formed by the oxidation of an organoglycolate ester using a hypohalide oxidizing agent, preferably under phase transfer conditions using a phase transfer catalyst. An example of a suitable oxidizing agent is sodium hypohalite, and a preferred starting material is methyl mandelate.

Abstract: 57 Phosphonomethylated amino acids can be prepared by reacting a dihalide of halomethylphosphonic acid with water to form a halomethylphosphonic acid followed by its reaction with the desired amino acid. Preferably, the process includes as an initial step the reaction of a phosphorus trihalide and formaldehyde to form the dihalide of halomethylphosphonic acid.
