Rhodium-catalyzed, P-directed selective C7 arylation of indoles.

The article discusses the research on the regioselective direct C7 arylation of indoles by directing groups. It mentions use of tertiary phosphine group in delivering rhodium catalysts to the carbon-hydrogen bond for the direct arylation of indole. Topics include the reactivity and selectivity of indole group, use of commercial Wilkinson's catalyst and synthesis of marine alkaloid dictyodendrin B.
