ABSTRACT:
A process for the preparation of optically active esters of 2-chloropropionic acid of the formula: ##STR1## from an optically active lactate of the formula: ##STR2## with inversion of configuration. COOR.sub.1 in formula I and formula II is a hydrolyzable group. The lactate of formula II is brought into contact with SOCl.sub.2, followed by decomposition of the chlorosulfite formed, the process being one in which at least the decomposition stage is carried out in the presence of an ether.
