α-carbon of the chiral 4-aryl-2-piperidinone product afforded chiral trans-3,4-disubstituted 2-piperidinone derivatives and reduction of the chiral 2-piperidinones with lithium aluminum hydride provided the corresponding enantiomerically pure trans-3,4-disubstituted piperidines. This methodology has been successfully applied to the synthesis of the anti-depressant paroxetine.
描述了一种由3-芳基戊二酸酐和(S)-甲基苄基胺制备手性4-芳基-2-哌啶酮的方便实用的方法。在手性4-芳基-2-哌啶酮产品的α-碳上进行酰化或烷基化,得到手性反式-3,4-二取代的2-哌啶酮衍生物,并用氢化铝锂还原手性2-哌啶酮,提供了相应的对映体纯的反式-3,4-二取代的哌啶。该方法已成功地应用于抗抑郁药帕罗西汀的合成。
