A new method for the preparation of chiral 4-substituted 2-piperidinones, trans-3,4-disubstituted 2-piperidinones, and trans-3,4-disubstituted piperidines is invented. Chiral paroxetine can be obtained from a chiral trans-3,4-disubstituted piperidine intermediate in high purity and good selectivity.
发明了一种制备手性4-取代2-哌啶酮、反式-3,4-二取代2-哌啶酮和反式-3,4-二取代哌啶的新方法。手性帕罗西汀可以从手性反式-3,4-二取代哌啶中间体高纯度和良好选择性地获得。
