摘要：
In this study, the successful use of organic solvent nanofiltration for the purification of three highly enantioselective quinine-based organocatalysts was demonstrated. Commercially available solvent-resistant membranes (DuraMem series) were utilized to remove specific impurities that originated from their respective synthesis pathways. DuraMem 200 exhibited the highest catalyst retention of 99%, which facilitated catalyst purification at the gram scale with a purity > 99 %.
