Abstract:
The reaction between L-aspartic acid and benzyloxycarbonyl chloride is carried out at a specific pH range, i.e., 12.0 to 13.5, whereby highly pure N-benzyloxycarbonyl-L-aspartic acid can be obtained in high yields, while both the by-production of N-benzyloxycarbonyl- alpha - or beta -L-aspartyl-L-aspartic acid and the decomposition of benzyloxycarbonyl chloride to benzyl alcohol are suppressed.
