Synthesis and characteristics of an aspartame analogue, L-asparaginyl L-3-phenyllactic acid methyl ester

Aspartame (L-aspartyl L-phenylalanine methyl ester) isan artificial sweetener as shown in Fig.1 (A) [1]. Studieson its structure and function showed that its N-terminalL-aspartyl residue could only be replaced by aminomalonyl[2] or L-asparaginyl [3] residue. When its peptide bondwas replaced by an ester bond [Fig. 1(B)] or the hydrogenof amide in the peptide bond replaced by a methyl group[Fig. 1(C)], its sweetness was lost [4]. According to thecrystal structure of aspartame, between the …
