An intramolecular Michael-type reaction, involving β′-amino-α,β-unsaturated ketone is used to prepare 2-mono- and 2,6-disusbtituted piperidines in a diastereoselective manner. This -strategy allows an easy access to 2,6- TRANS-piperidine, starting from either E- or Z-olefin configuration.
涉及β'-氨基-α,β-不饱和酮的分子内迈克尔型反应用于以非对映选择性方式制备2-单-和2,6-二取代的哌啶。这种策略允许从 E- 或 Z- 烯烃构型开始轻松获得 2,6- 反式哌啶。
