The four chiral centres in posaconazole (POS) result in as many as 16 chiral isomers. Controlling all the chiral impurities in POS is a challenging task. In this study, three high-risk chiral impurities were identified and synthesized, and the corresponding chemical structures were characterized. Three single crystals were obtained and analyzed to support the absolute configuration elucidation. Based
