It takes two to tango: A domino multicatalytic synthesis of dihydroquinolines is realized, wherein the products of a rhodium‐catalyzed arylation of alkynes are cyclized by a palladium‐promoted CN cross‐coupling (see scheme). The combination of catalysts with potentially exchangeable ligands is remarkable as each metal–ligand combination affords specific reactivity and selectivity.
探戈需要两个步骤:实现了多氢喹啉的多米诺骨牌多催化合成,其中铑催化的炔烃芳基化产物通过钯促进的CN交叉偶联而环化(参见方案)。催化剂与潜在可交换配体的组合非常引人注目,因为每种金属-配体组合均可提供特定的反应性和选择性。
