| titleOfInvention | Preparation of nalpha-acyl-dl-amino acid |
| abstract | PURPOSE: To obtain the title compound by the easy racemization of optically active N α -acylamino acid with an acitve ester of aliphatic acid in the presence of a tertiary amine and 1-hydroxybenzotriazole (HOBT). n CONSTITUTION: The title compound is obtained by the reaction of an optically active N α -acylamino acid with an active ester of aliphatic acid at room temp.W 100°C in the presence of a tertiary amine (example; triethyl amine, etc.) and 1- hydroxybenzotriazole (HOBT) using a solvent, e.g. DMSO. Preferable amino acid of the optically active N α -acylamino acid is natural or synthetic and neutral, acidic or basic amino acid. The acyl group is, e.g. benzoyl groups, formyl groups, etc. This invention is useful for the racemization of residual amino acids after the separation of the desired optically active amino acid in the amino acid resolution with acylase. n COPYRIGHT: (C)1980,JPO&Japio |
