We report a new method for the preparation of chiral 2-aryl-2-fluoropropanoic acids, including 2-fluoroibuprofen, a fluorinated analogue of non-steroidal anti-inflammatory drugs (NSAIDs), by the kinetic resolution of racemic 2-aryl-2-fluoropropanoic acids using enantioselective esterification. By applying pivalic anhydride (Piv2O) as a coupling agent, bis(α-naphthyl)methanol [(α-Np)2CHOH] as an achiral
我们报告了一种制备手性 2-芳基-2-氟丙酸的新方法,包括 2-氟布洛芬,一种非甾体抗炎药 (NSAID) 的氟化类似物,通过外消旋 2-芳基-2 的动力学分辨率-氟丙酸使用对映选择性酯化。通过应用新戊酸酐 (Piv2O) 作为偶联剂,双 (α-萘基) 甲醇 [(α-Np)2CHOH] 作为非手性醇,和 (+)-苯并四甲醚 (BTM) 作为手性酰基转移催化剂,一系列外消旋 2-芳基-2-氟丙酸被动力学分离,以提供光学活性羧酸和相应的酯,具有良好到高度的对映体过量。
