Described here is a general and highly efficient method for the synthesis of 1H- and 3H-indoles. In the presence of CBr4and a suitable base, the cyclization ofN-aryl enamines proceeds with high efficiency. Unlike previous intramolecular cross d

The nBu4NI-catalyzed intramolecular cross-dehydrogenative coupling (CDC) reaction has been applied to the synthesis of 1H-indole derivatives. Intramolecular oxidative coupling of N-arylenamines proceeded in the presence of a catalytic amount of nBu4NI and tert-butyl hydroperoxide (TBHP) to afford the corresponding 1H-indole derivatives in good-to-excellent yields. A preliminary study of the synthesis of 3H-indole is also reported. This is a rare example of the nBu4NI-catalyzed C-C bond-forming CDC reaction. Copyright
