Abstract: The present invention relates to a process for the preparation of optically active 2--halopropionic acids, in which the corresponding optically active alkyl 2--halopropionates are caused to react with a carboxylic acid at elevated temperature in a transacylation reaction with the formation of the optically active 2--halopropionic acid and the alkyl carboxylate, and the optically active 2--halopropionic acid obtained is separated from the reaction mixture. The optically active products produced are important intermediates for the preparation of plant protectants and pharmaceuticals.

Abstract: A process for the preparation of (L)-2-chloropropionic acid and its alkali metal, alkaline earth metal or ammonium salts which comprises hydrolyzing isobutyl L-chloropropionate at a pH of from 4 to 8 in the presence of a lipase from Pseudomonas spec. DSM 8246 and isolating the optically active reaction product from the reaction mixture either directly or after conversion of the salt into the acid in a conventional way, or further reacting it in situ. The optically active products are important intermediates for preparing crop protection agents.
