Abstract
Ultrasonic waves applied during the crystallization of slightly enantiomeric-enriched, supersaturated, aqueous solutions of dl-threonine lead to strong chiral amplifications (up to 90 % ee), particularly at the first stages of the crystallization process (see figure). The findings are confirmed by the optical rotation and circular-dichroism experiments of the crystallization solutions.
