The present invention provides a process for simply producing an optically active 2-thiomethyl-3-phenylpropionic acid derivative useful as an intermediate for medicines from inexpensive raw materials. An optically active 2-hydroxymethyl-3-phenylpropionic acid ester derivative which can be relatively easily obtained by asymmetric reduction reaction with an enzyme is cyclized to an optically active P-lactone derivative which is then reacted with a sulfur compound to produce an optically active 2-thiomethyl-3-phenylpropionic acid derivative in high yield.

The absolute configuration of fasidotril has been established by a chemical correlation leading to the stereochemical assignment of the intermediate (S)-3-acetylsulfanyl-2-(benzo[1,3]dioxol-5-ylmethyl)propanoic acid. (C) 2003 Elsevier Ltd. All rights reserved.
