  • Synthesis of N-[N-(3,3-dimethylbutyl)-L-?-aspartyl]-L-phenylalanine 1-methyl ester using 3,3-dimethylbutyraldehyde precursors
    Patent number: 8034969
    Abstract: N—[N-(3,3-dimethylbutyl)-L-?-aspartyl]-L-phenylalanine 1-methyl ester is produced by hydrogenation of L-?-aspartyl-L-phenylalanine 1-methyl ester and 3,3-dimethylbutyraldehyde produced in situ by the hydrolysis or cleavage of a 3,3-dimethylbutyraldehyde precursor. The production method is efficient and low cost, as compared with conventional N—[N-(3,3-dimethylbutyl)-L-?-aspartyl]-L-phenylalanine 1-methyl ester synthesis.
    Type: Grant
    Filed: May 12, 2010
    Date of Patent: October 11, 2011
