zirconium-mediated synthesis of allylamines from simple amines and enol ethers is described. This strategy also allows the synthesis of amino alcohol derivatives containing a Z double bond in their structure when 2,3-dihydrofuran is used. Simple conventional modification of these amino alcohols leads to 2-substituted piperidine derivatives. By applying this approach, a formal total synthesis of the alkaloid
描述了一种简单有效的锆介导的由简单胺和烯醇醚合成烯丙胺的方法。当使用2,3-二氢呋喃时,该策略还允许合成在其结构中包含Z双键的氨基醇衍生物。这些氨基醇的简单常规修饰产生2-取代的哌啶衍生物。通过应用这种方法,可以轻松地从受保护的丁胺中完成生物碱亚氨酸的正式全合成。最后,取决于起始胺的结构,锆介导的胺和烯丙基苯基醚的反应提供了均烯丙基胺或氨基醚。
