    摘要:
    报道了药学上重要的 N-(杂)芳基哌啶的一种新的通用从头合成。该协议使用稳健的非对映选择性还原胺化/氮杂-迈克尔反应序列,以从广泛可用的杂环胺亲核试剂和羰基亲电试剂开始,快速构建复杂的多取代环系统。值得注意的是,该过程的非对映选择性因水的存在而增强,并且 DFT 计算支持立体化学模型,该模型涉及水配位烯醇中间体的面部选择性质子化。

    Treatment of 2-methoxycarbonyl- (or 3-cyano-)allyl acetoacetates with a tertiary amine or triphenylphosphane afforded α-methylene γ-substituted δ-keto esters (or nitrile) in satisfactory yields. Various bases and nucleophiles were tested to elucidate the mechanism. The results of the study strongly suggest an intermolecular pathway involving a SN2′-decarboxylation-SN2′ cascade.
