Process for producing optically pure 2- (4-hydroxyphenoxy) -propionic acid compound |
| abstract |
On an industrial scale, R-2 is substantially free of excess alkylation products, is not contaminated with highly colored by-products, and therefore does not require any complicated or expensive purification procedures, R-2 A simple method for producing-(4-hydroxyphenoxy) propanoic acid. An optically pure R-hydroxyphenoxypropanoic acid or a salt or ester thereof is produced by reacting hydroquinone or a salt thereof with S-halopropanoic acid or a salt thereof in the presence of a mild reducing agent. how to.
