  Divergent Reaction Pathways of Homologous and Isosteric Propargyl Amides in Sequential Ru/Pd-Catalyzed Annulations for the Synthesis of Heterocycles

  摘要：

  Cu-catalyzed three-component coupling of imines with benzoyl chloride and terminal arylalkynes followed by enyne ring-closing metathesis (RCM) and Heck cyclization afforded medicinally relevant benzoindolines, cyclopropane-fused indenopyridines, pyrroloquinolines, or 1,7-tetrahydrophenanthrolines via divergent cyclization pathways. Unexpectedly, the Pd-catalyzed cyclization of heterocyclic dienes proceeded via regiodivergent 5-exo or 6-endo pathways depending on the ring size (n = 1, 2) or the presence of isosteric groups (CH vs N). A one pot protocol for the enyne-RCM/Heck annulation featuring a sequential addition of the Ru and Pd catalysts was developed maximizing the synthetic efficiency.

• Modular strategy for the synthesis of functionalized aryl-fused azabicyclo[2.2.2]octanes via radical-mediated cascade cyclization

  A two-step synthesis of rare 2-azabicyclo[2.2.2]octanes is described. N-propargyl amides obtained via Cu(I)-catalyzed three-component coupling, underwent radical-mediated cascade cyclization to afford 5,6-aryl-fused 2-azabicyclo[2.2.2]octanes with arylidene functionality on the two-carbon bridge in 43–62% yields. Phenylidene and 1-naphtylidene derivatives were obtained exclusively as Z diastereomers

  描述了稀有的2-氮杂双环[2.2.2]辛烷的两步合成。通过Cu（I）催化的三组分偶联获得的N-炔丙基酰胺进行自由基介导的级联环化反应，从而在二碳桥上得到具有亚芳基官能团的5,6-芳基稠合的2-氮杂双环[2.2.2]辛烷收率为43-62％。亚苯基和1-萘基衍生物仅作为Z非对映异构体获得，而亚芳基取代基中的富电子基团提供了以2.3∶1M的比例有利于Z非对映异构体的产物混合物。
