anti-inflammatory drug (NSAID) used to relieve pain and inflammation associated with osteoarthritis. Herein a new and practical method for the preparation of 1 from 4-bromo-2-fluorobiphenyl (2) is reported, which achieves a good overall yield (20%) and high enantioselectivity (96%). This method avoids the use of expensive catalysts and affords the possibility of large-scale manufacturing with simple operations
摘要 ( S )-Flurbiprofen ( 1 ) 是一种非甾体抗炎药 (NSAID),用于缓解与骨关节炎相关的疼痛和炎症。本文报道了一种从 4-溴-2-氟联苯 ( 2 ) 制备1的新实用方法,该方法具有良好的总收率 (20%) 和高对映选择性 (96%)。这种方法避免了使用昂贵的催化剂,并提供了通过简单操作进行大规模制造的可能性。
