  Multicomponent Multicatalyst Reactions (MC)²R: One-Pot Synthesis of 3,4-Dihydroquinolinones

  摘要：

  A Rh/Pd/Cu catalyst system led to an efficient synthesis of dihydroquinolinones in one-pot, two operations. The reaction features the first triple metal-catalyzed transformations in one reaction vessel, without any intermediate workup. The conjugate-addition/amidation/amidation reaction sequence is highly modular, divergent, and practical.

  choice: The palladium‐catalyzed cascade reaction of 2‐chloroaryl sulfonates with arylamine and amide nucleophiles provides direct access to N‐arylbenzimidazoles. This strategy selectively produces the heterocycles based on chemoselective oxidative addition. 2‐Chloroaryl triflates (Tf) produce one regioisomer and the corresponding 2‐chloroaryl mesylates (Ms) deliver the other in a selectable manner.

  通过选择：钯催化的 2-氯芳基磺酸盐与芳胺和酰胺亲核试剂的级联反应可直接获得N-芳基苯并咪唑。该策略基于化学选择性氧化加成选择性地产生杂环。2-氯芳基三氟甲磺酸酯 (Tf) 产生一种区域异构体，相应的 2-氯芳基甲磺酸酯 (Ms) 以可选择的方式传递另一种。
