  α,β-不饱和亚胺通过 C−H 键活化的立体选择性烷基化

  摘要：

  α,β-不饱和亚胺通过 CH 活化进行立体选择性烷基化，然后亚胺水解产生三和四取代的 α,β-不饱和醛。在铑催化剂存在下，衍生自异丁烯醛、巴豆醛和tiglic 醛的α,β-不饱和N-苄基亚胺在β-位进行定向C-H 活化，并与末端烯烃和炔烃反应形成三-和具有非常高立体选择性的四取代 α,β-不饱和亚胺。水解以提供 α,β-不饱和醛可以在保持β-烷基化亚胺产物立体化学的仔细控制的条件下进行。或者，对于甲基丙烯醛的 N-苄基亚胺的 β-烷基化产物，可以在提供完全异构化为 E 异构体的条件下进行水解。

  日期：2006.5.1

  alkylation of α,β-unsaturated imines via C−H activation followed by imine hydrolysis produces tri- and tetrasubstituted α,β-unsaturated aldehydes. In the presence of a rhodium catalyst, α,β-unsaturated N-benzyl imines derived from methacrolein, crotonaldehyde, and tiglic aldehyde undergo directed C−H activation at the β-position and react with terminal alkenes and alkynes to form the tri- and tetrasubstituted
