The reaction involving the resolution of DL-PL through the intervention of D-Lac is a highly specific process. DL-PL undergoes hydrolysis under the influence of D-Lac, leading to the formation of D-pantoic acid. The latter is subsequently subjected to lactonization, resulting in the production of D-PL. Any remaining unreacted L-pantolactone can be deracemized by repeated hydrolysis, ultimately yielding DL-PL.
