An electrocatalytic reaction protocol is developed for achieving intramolecular dehydrogenative annulation of N-aryl enamines. It offers a simple and efficient way for the synthesis of indoles in an undivided cell. Good to excellent yields are obtained un

A rhodium-catalyzed intermolecular coupling between arylnitrones and diazo compounds by C-H activation/[4 + 1] annulation with a C(N2)-C(acyl) bond cleavage is reported, and 2,3-disubstituted NH indoles are directly synthesized in up to a 94% yield. A variety of functional groups are applicable to this reaction to give the corresponding products with high selectivity. Compared to other previously reported Rh(III)-catalyzed synthesis of homologous series, this method is simpler, more general, and more efficient.

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
Palladium-catalyzed intramolecular trapping of the blaise reaction intermediate for tandem one-pot synthesis of indole derivatives
Kim, Ju Hyun,Lee, Sang-Gi
supporting information; experimental part, p. 1350 - 1353 (2011/06/10)
Palladium-catalyzed intramolecular N-arylative and N-alkylative/N-arylative trappings of the Blaise reaction intermediates could be a new route to construct the indole moiety in a tandem one-pot manner from nitriles.
