    摘要: A method of preparing .alpha.-APM derivatives without using an expensive L-phenylalanine is provided, wherein 2,5-dioxopiperazine-3-acetamide is reacted with acetic anhydride to give N,N'-diacetyl-6-cyanomethyl-2,5-dioxopiperazine, which is then reacted with benzaldehyde in the presence of a strong base to give 1-acetyl-3-benzylidene-6-cyanomethyl-2,5-dioxopiperazine. This is treated with hydrazine to give 3-benzylidene-6-cyanomethyl-2,5-dioxopiperazine, which is then reduced to prepare 3-benzyl-6-cyanomethyl-2,5-dioxopiperazine, which is converted by reaction with methanol in the presence of a strong acid to an .alpha.-APM derivative for use as a sweetener.
