Iodine(III) reagents are used in catalytic one‐pot reactions, first as both oxidants and substrates, then as cross‐coupling partners, to afford chiral polyfunctionalized amines. The strategy relies on an initial catalytic auto C(sp3)−H amination of the iodine(III) oxidant, which delivers an amine‐derived iodine(I) product that is subsequently used in palladium‐catalyzed cross‐couplings to afford a
碘(III)试剂用于催化一锅法反应,首先用作氧化剂和底物,然后用作交叉偶联伙伴,以提供手性多官能胺。该策略依赖于碘(III)氧化剂的初始催化自动C(sp 3)-H胺化反应,该胺可提供胺衍生的碘(I)产品,该产品随后用于钯催化的交叉偶联中,从而提供多种具有高产量和出色的立体选择性的有用构建基块。这项研究证明了高价碘试剂的自我胺化的概念,这增加了芳基部分的价值。
