| abstract | PURPOSE: To carry out the optical resolution of an amine with a resolution reagent available from an ordinary raw material easily at a high optical purity, by using an optically active α-phenyl-propionic acid derived from an optically active lactic acid as the optical resolution reagent. n CONSTITUTION: An optically active α-phenylpropionic acid derived from an optically active lactic acid is used as the optical resolution reagent. The reagent is made to react with a mixture of optical isomers of an amine to form diastereomer salts, and on of the salts is separated e.g. by crystallization. The required diastereomer salt is hydrolyzed to obtain an optically active amine. The resolution reagent can be prepared easily, in an optical yield of ≥60% and optical purity of ≥90% by (1) sulfonyloxylating the hydroxyl group of an optically active lactic acid by conventional method, an (2) reacting the product with benzene in the presence of a Lewis acid catalyst such as aluminum chloride. The obtained reaction product can be used as the reagent without purification. n COPYRIGHT: (C)1986,JPO&Japio |
