Abstract

N-[N-(3,3-dimethylbutyl)-L-alpha-aspartyl]-L-phenylalanine 1-methyl ester is produced by hydrogenation of a mixture of 3,3-dimethylbutyraldehyde and a precursor of L-alpha-aspartyl-L-phenylalanine 1-methyl ester. In particular, N-[N-(3,3-dimethylbutyl)-L-alpha-aspartyl]-L-phenylalanine 1-methyl ester is produced using an acid salt of L-alpha-aspartyl-L-phenylalanine 1-methyl ester or N-protected L-alpha-aspartyl-L-phenylalanine 1-methyl ester. The production method is efficient and low cost, as compared with conventional N-[N-(3,3-dimethylbutyl)-L-alpha-aspartyl]-L-phenylalanine 1-methyl ester synthesis.
