Highway to the hydrazone: A hypervalent iodide initiated cascade process enables the rapid union of an aldehyde, an allylic hydrazide, and an alcohol (see scheme; Pv=pivaloyl). This process affords a diverse range of functionalized ether adducts, while simultaneously generating a stereodefined alkene and two new vicinal stereocenters. The use of chiral non‐racemic hydrazines and alcohols offers a rapid
通往的道路:高碘化物引发的级联过程可实现醛,烯丙基酰肼和醇的快速结合(请参阅方案; Pv =新戊酰)。此过程提供了多种功能化的醚加合物,同时生成了立体定义的烯烃和两个新的邻位立体中心。使用手性非外消旋肼和醇可快速进入复杂的“类天然产物”结构。
