Abstract The synthesis of two isomers of Aprepitant (APT) and three isomers of Fosaprepitant (FPT), crucial components for quality control in manufacturing, is described. Herein, threechiralcenters in the isomers of Aprepitant are established in high yield by induced crystallization and chiralreduction. Additionally, the isomers of Aprepitant are utilized to synthesize the isomers of Fosaprepitant
