NEW SYNTHESIS OF SUBSTITUTED INDOLE DERIVATIVES VIA VICARIOUS NUCLEOPHILIC SUBSTITUTION OF HYDROGEN
Wojciechowski, K.,Makosza, M.
, p. 4793 - 4794 (2007/10/02)
Carbanions bearing leaving groups react with m-nitrophenyl isocyanides to form products of vicarious nucleophilic substitution of hydrogen which subsequently cyclize to corresponding indoles.
