摘要:
Processes for producing optically active ester derivatives are disclosed. According to the present invention an optically active aryloxyphenoxy propionate derivative is produced by reacting a chlorinated heterocyclic aromatic compound with (2R)-2-(4-hydroxyphenoxy)propionic acid tetrahydrofurfuryl ester in an anhydrous solvent in the presence of a base. According to the present invention, an optically active propionate derivative of the formula [I] ##STR1## (wherein R represents hydrogen or 3-chloro-5-trifluoromethyl-2-pyridyl group) is produced by reacting a corresponding optically active methyl propionate derivative with tetrahydrofurfuryl alcohol, or by reacting a corresponding optically active propionic acid derivative with tetrahydrofurfuryl alcohol, or by reacting (2S)-tetrahydrofurfuryl 2-chloropropionate with a corresponding phenol derivative in specific conditions.
