Halogenation Heck cyclization

In conclusion, the fantastically diverse chemistry of indole has been significantly enriched by palladium-catalyzed reactions. The accessibility of all of the possible halogenated indoles and several indolyl triflates has resulted in a wealth of synthetic applications as witnessed by the length of this chapter. In addition to the standard Pd-catalyzed reactions such as Negishi, Suzuki, Heck, Stille and Sonogashira, which have had great success in indole chemistry, oxidative coupling and cyclization are powerful routes to a variety of carbazoles, carbolines, indolocarbazoles, and other fused indoles. [Pg.163]

Heck-type cyclization of oxime ethers which contain a halogenated aryl group is a new route to dihydroindole oxime ethers. Thus, oxime ethers 70 in the system Pd(PPh3)4/ K2C03/dioxane afforded dihydroindoles 71 in 59-89% yields (equation 30) °. ... [Pg.244]
