Step and redox efficiencies are a rising priority in synthetic method development, in order to make synthetic processes more sustainable and more affordable. Herein, a step and redox efficient nitroarene to indole synthesis is developed, in sharp contrast to the rich literature on the construction of indoles. Elemental zinc was found to be the best terminal reductant. This journal is
A Fast Track to Indoles and Annulated Indoles through ortho- vs ipso-Amination of Aryl Halides

A complementary site selective ortho- vs ipso-amination of aryl halides using non-electrophilic amine sources for construction of indole scaffolds is reported. A palladium-catalyzed alkyne insertion/C-H activation/palladacycle amination via merger of three easily diversified components including iodoarenes, alkynes, and amines delivers indoles with different substitution patterns even in gram scales. By employing ortho-bromoanilines, a consecutive annulative π-extension of indoles proceeds to construct indolo[1,2-f]phenanthridine scaffolds via four C-C and C-N bond formations in one pot.

The indolization of deoxybenzoin o,m,p (Me, MeO, Cl), p-NO2 and m-EtO-phenylhydrazones (1) by the above reaction has been examined.All the reactions are carried out at room temperature and high yields of the corresponding indoles (2) are obtained even whe
