Abstract
A process for producing (+)-2-amino-1-butanol comprising optically resolving an N-acyl-DL-aminobutyric acid using an acylase to obtain L-2-aminobutyric acid and an N-acyl-D-aminobutyric acid which is recycled after racemization, esterifying the L-2-aminobutyric acid to form L-2-aminobutyric acid ester, and reducing the L-2-aminobutyric acid ester to form (+)-2-amino-1-butanol.
