A method for the synthesis of N-(phosphonomethyl) glycine or one of its derivatives selected from the group of its salts, its phosphonate esters and its phosphonate ester salts, including the steps of: a) forming a reaction mixture having an acid catalyst, N,N′-bis(carboxymethyl)-2,5-diketopiperazine and a compound having one or more P—O—P anhydride moieties, wherein the moieties have one P atom at the oxidation state (+III) and the other P atom at the oxidation state (+III) or (+V), to form N,N′-bis(phosphonomethyl)-2,5-diketopiperazine, its dehydrated forms or their phosphonate esters; b) hydrolyzing the reaction mixture to form N-(phosphonomethyl)glycine or one of its derivatives selected from the group consisting of its salts, its phosphonate esters and its phosphonate ester salts.
一种合成N-(磷酸甲基)甘氨酸或其盐类、磷酸酯或磷酸酯盐类衍生物的方法,包括以下步骤:a)形成反应混合物,其中包括酸催化剂、N,N′-双(羧甲基)-2,5-二酮哌嗪和具有一个或多个P—O—P酐基团的化合物,其中酐基团具有一个P原子在氧化态(+III),另一个P原子在氧化态(+III)或(+V),以形成N,N′-双(磷酸甲基)-2,5-二酮哌嗪、其脱水形式或其磷酸酯;b)水解反应混合物,以形成N-(磷酸甲基)甘氨酸或其盐类、磷酸酯或磷酸酯盐类衍生物之一。
