, p. 4821 - 4824 (2007)
(Chemical Equation Presented) Gold-catalyzed intramolecular hydroarylation of allenic anilines and phenols offers an efficient route to dihydroquinoline and chromene derivatives under mild reaction conditions. The hydroarylation takes place at the terminal or central allenic carbon depending on the substrate structure, leading to a highly selective formation of six-membered rings.

(Chemical Equation Presented) 2,3-Dihydroindoles, 1,2,3,4- tetrahydroquinolines, and 2,3,4,5-tetrahydrobenzo[b]azepines are available by a process that represents formal radical cyclization onto aromatic rings. Optically pure benzo-fused heterocycles are also accessible by this method. p-Iodophenols, especially those with the phenolic oxygen protected as a MOM-ether, can be coupled with amino alcohols to produce N-aryl amino alcohols, which can be converted into the corresponding alkyl iodides in which the nitrogen is protected as a carbamate. These compounds give cross-conjugated ketones after removal of the phenolic protecting group and oxidation with PhI(OAc)2 in the presence of MeOH. The ketones undergo 5-, 6- or 7-exo-trigonal radical cyclization, and then exposure to acid, or sequential treatment with a Grignard reagent and then acid, effects rearomatization to produce the benzo-fused nitrogen heterocycles.
