Lower and higher homologs, l-2-amino-4-(p-methoxyphenyl)butanoic acid (l-Amb) and l-2-amino-6-(p-methoxyphenyl)hexanoic acid (l-Amh), of l-2-amino-5-(p-methoxyphenyl)pentanoic acid were prepared by optical resolution of N-acetyl-Dl-Amb and of N-acetyl-Dl-Amh with Aspergillus acylase. N-Acetyl-Dl-Amb or N-acetyl-Dl-Amh was synthesized from [2-(p-methoxyphenyl)ethyl or butyl](acetamido)malonic acid by heating with p-xylene.
