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.
