  Ru(III)-Catalyzed Cyclization of Arene-Alkene Substrates via Intramolecular Electrophilic Hydroarylation

  摘要：

  We herein report that RuCl3/AgOTf has proven to be a hydroarylation catalyst with an efficiency and scope superior to previously known methods. This catalyst demonstrated consistent performance with arene-ene substrates of diverse structural features, providing good to excellent yields of cyclization products (chromanes, tetralins, terpenoids, dihydrocoumarins).

• Enantioselective Fujiwara-Moritani Indole and Pyrrole Annulations Catalyzed by Chiral Palladium(II)-NicOx Complexes

  catalytic asymmetric Fujiwara-Moritani ring closures of several indole- and pyrrole-based cyclization precursors are reported. These unprecedented oxidative palladium(II)-catalyzed annulations allow for the formation of a stereogenic quaternary carbon atom, and decent levels of enantiocontrol are seen in 5-exo-trig cyclizations (54 % ee for an indole and 76 % ee for a pyrrole) while 6-exo-trig ring

• Catalytic C−H Bond Functionalization with Palladium(II):  Aerobic Oxidative Annulations of Indoles
  作者：Eric M. Ferreira、Brian M. Stoltz

  DOI：10.1021/ja035054y

  日期：2003.8.1

  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.
