The non-conventional hydrolysis of mixtures of diastereoisomeric α-bromo acetals, available in high yields, high diastereomeric excesses, and in large amounts, allows the synthesis and the full characterization of enantiomerically pure (2S)- and (2R)-bromoalkyl aryl ketones. The developed methodology represents the first route to enantiomerically pure 2-bromoalkyl aryl ketones of (2R) and (2S) configurations.
非传统的水解法对混合的二对映异构体α-溴醛的处理,可在高产率、高对映体过量和大量条件下实现,允许合成和全面表征对映体纯的(2S)-和(2R)-溴烷基芳基酮。所开发的方法代表了获得(2R)和(2S)构型的对映体纯2-溴烷基芳基酮的第一条途径。
