Indole derivatives are of great importance because of their biological activity and application in technology. This study explores the synthesis of 2-alkylated indoles derivatives and 2,2′-bis(indolyl)methanes, and their application in anion sensing. The synthesis of a wide range of 2-alkylated indoles and some 2,2′-bis(indolyl)methanes, which cannot be synthesized by previously reported methods, was for the first time accomplished employing dipole exchange of the indole ring towards electrophilic substitution. Some of the indole derivatives exhibited selective recognition and sensing ability towards F- and HSO4- anions through naked-eye detectable color changes. The sensing details of the indole derivatives were also evaluated using UV-Vis spectroscopy and 1H NMR titration techniques.

A directing-group-controlled, copper-catalyzed divergent approach to indoles and oxazoles from enamides has been developed. The picolinamide-derived enamides undergo the intramolecular aromatic C-H amination in the presence of a Cu(OPiv)2 catalyst and an MnO2 oxidant to form the corresponding indoles in good yields. On the other hand, simpler aryl- or alkyl-substituted enamides are converted to the 2,4,5-trisubstituted oxazole frameworks via vinylic C-H alkoxylation under identical conditions. The copper catalysis can provide uniquely divergent access to indole and oxazole heteroaromatic cores of great importance in medicinal and material chemistry.
