it was first observed by chemist paul walden in 1896. he was able to convert one enantiomer of a chemical compound into the other enantiomer and back again in a so-called walden cycle which went like this: (+) chlorosuccinic acid (1 in "scheme 1") was converted to (+) malic acid 2 by action of silver oxide in water with retention of configuration, in the next step the hydroxyl group was replaced by chlorine to the other isomer of chlorosuccinic acid 3 by reaction with phosphorus pentachloride, a second reaction with silver oxide yielded (-) malic acid 4 and finally a second reaction with pcl returned the cycle to its starting point.
