Reaction Steps
The sequence of reactions in Reaction Scheme 9a is comparable to those set forth in Reaction Scheme 9 except that N-acetylglycine XVIII is deacylated to form 2,5-diketopiperazine XXX. 2,5-diketopiperazine XXX is then reacted with formaldehyde and H3PO3, PCl3 or other H3PO3 source to produce N-(phosphonomethyl)glycine I and acetic acid. Acetic acid which is produced in the hydrolysis step can be reacted with ammonia to generate acetamide for the carboxymethylation step.
