실험 절차

An alternative route for the preparation of glyphosate I from acetamide VII is illustrated in Reaction Scheme 7 ##STR15## In general, the sequence of reactions in Reaction Scheme 7 is the same as those in Reaction Scheme 6 except that N-acetyliminodiacetic acid XVI is deacylated to form 1,4-di(carboxymethyl)-2,5-diketopiperazine XVII which is then directly phosphonomethylated in the same manner as iminodiacetic acid XIV is phosphonomethylated in Reaction Scheme 6.
