Synthesis of indole derivatives from 2-bromoanilines by a palladium-assisted reaction
In the presence of palladium(II) acetate, 2-bromoanilines readily react with enamines such as N-vinyl-pyrrolidone or α-piperidinostyrene to produce indole derivatives.
Palladium-catalyzed synthesis of 2-substituted indoles
The palladium(0)-catalyzed cross-coupling reaction of alkynylstannanes with 2-bromoanilines or 2-trifloxyanilines results in the formation of 2-alkynylanilines. The coupling reaction tolerates
General and Facile Synthesis of Indoles with Oxygen-Bearing Substituents at the Benzene Moiety
Indoles with oxygen-bearing substituents such as a methoxy or (triisopropylsilyl)oxy group at all of the positions of the benzene moiety were synthesized by cyclization of tert-butyl methoxy(or
Indole synthesis by radical cyclization of o-alkenylphenyl isocyanides and its application to the total synthesis of natural products.
TLDR
The utility of tin-mediated radical cyclization of o-alkenylphenyl isocyanide for indole synthesis was demonstrated by application to synthetic studies on gelsemine and discorhabdin A, and the total synthesis of an aspidosperma alkaloid, (-)-vindoline.
Enantioselective total synthesis of FR900482.
TLDR
The development of two approaches for the enantioselective total synthesis of FR900482 are described, where the N-hydroxybenzazocine ring could be constructed directly from an omega-formylnitrobenzene derivative by intramolecular reductive hydroxylamination.
