Abstract: Process for the preparation of an optically active 2-chloropropionate ester of formula: R being an optionally substituted hydrocarbyl residue, from an optically active lactate of formula the said process being characterised in that the said lactate (I) is brought into contact with phosgene and a compound chosen from aliphatic amides, aliphatic lactams and aliphatic ureas. Use of the process for the manufacture of intermediates which are useful in the agrochemical industry.

Abstract: PR?CIS DE LA DIVULGATION L'invention concerne un procédé de préparation d'ester d'acide chlorocarboxylique optiquement actif à partir de l'ester d'acide .alpha.-hydroxy carboxylique correspondant. Ce procédé qui a l'avantage d'offrir d'excellents rendements tout en conservant une excellente activité optique, est caractérisé en ce que l'on met en contact l'ester d'acide .alpha.-hydroxy carboxylique avec du phosgène et un composé choisi parmi les amides aliphatiques, les lactames aliphatiques et les urées aliphatiques. Ce procédé est notamment utilisable à la fabrication d'intermédiaires utiles dans l'industrie agrochimique, tels que des esters de 2-chloropropionate.
