We report a general visible-light-mediated strategy that enables the construction of complex C(sp3)-rich N-heterospirocycles from feedstock aliphatic ketones and aldehydes with a broad selection of alkene-containing secondary amines. Key to the success of this approach was the utilization of a highly reducing Ir-photocatalyst and orchestration of the intrinsic reactivities of 1,4-cyclohexadiene and
我们报告了一种一般可见光介导的策略,该策略能够从原料脂肪族酮和醛中构建复杂的富含 C(sp3) 的 N-heterospirocycles,并具有多种含烯烃的二级胺。这种方法成功的关键是利用高度还原的 Ir 光催化剂和协调
