  Catalytic C−H Bond Functionalization with Palladium(II):  Aerobic Oxidative Annulations of Indoles

  摘要：

  A palladium-catalyzed aerobic oxidative annulation of indoles is described. We have demonstrated that a variety of factors influence these cyclizations, and in particular the electronic nature of the pyridine ligand is crucial. It is also remarkable that these oxidative cyclizations can proceed in good yield despite background oxidative decomposition pathways, testament to the facile nature with which molecular oxygen can serve as the direct oxidant for Pd(0). We have also shown that the mechanism most likely involves initial indole palladation (formal C-H bond activation) followed by migratory insertion and beta-hydrogen elimination.

  conjunction with the chiral spiro bis(isoxazoline) ligand (SPRIX). The presence of an N-allyl substituent on the substrate has a strong impact on both reactivity and selectivity, leading to tricyclic indole products (up to 96% ee) with a chiral quaternary carbon center.

  通过Pd（OCOCF 3）2和手性螺双（异恶唑啉）配体（SPRIX）建立了通过C–H活化的3-烯基吲哚的高对映选择性环化反应。底物上N-烯丙基取代基的存在对反应性和选择性都有很强的影响，导致具有手性季碳中心的三环吲哚产物（至多96％ee）。
