Iridium-catalyzed acceptorless dehydrogenative coupling of tertiary amines and arylamines has been developed. A number of benzimidazoles were prepared in good yields. An iridium-mediated C-H activation mechanism is suggested. This finding represents a novel strategy for the synthesis of benzimidazoles.

An efficient metal-free, (NH4)2S2O8 mediated intramolecular oxidative cyclization for the construction of polycyclic heterocycles was disclosed. A series of polycyclic quinazolinone derivatives with good functional group tolerance were obtained in high yields. The natural products tryptanthrin and rutaecarpine, as well as their derivatives, were easily synthesized by this strategy. A preliminary mechanism study suggested the carbon-centered radical was involved in the catalytic cycle.
Reaction of N-Nitroaryl-1,2,3,4-tetrahydroisoquinoline Derivatives with Oxygen

, p. 367 - 369 (2007/10/02)
Heating N-4'-methyl-2'-nitrophenyl-1,2,3,4-tetrahydroisoquinoline (1) in the presence of oxygen gave both products derived from cleavage of the C8a-Cl bond and oxidation at the 1-position.Under similar conditions N-4'-nitrophenyl-1,2,3,4-tetrahydroisoquin
