methods for the synthesis and purification of chiral organic compounds is a challenge in modern science and technology. Pharmaceutically and agro-chemically important compounds are especially required in optically pure form. We report the racemic mixture synthesis of β-perfluoroalkyl α-amino acids, which is based on the In-mediated addition of perfluoroalkyl radicals to dehydroamino acids followed by asymmetric
开发有效的手性有机化合物合成和纯化方法是现代科学技术面临的挑战。尤其需要光学纯形式的药学和农业化学上重要的化合物。我们报告了 β-全氟烷基 α-氨基酸的外消旋混合物合成,该合成基于全氟烷基自由基与脱氢氨基酸的 In 介导加成,然后不对称质子化。所有对映异构体都可以通过使用单个手性 HPLC 色谱柱进行分离,而无需正交使用氟色谱柱。
