摘要:
A chemoenzymatic method is disclosed for preparing N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester via the enzymatic regioselective hydrolysis of neotame esters using lipases or esterases.
摘要:
This invention relates to the purification of N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester by resolving a mixture of the alpha- and beta-isomers of N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester using metal ions.
