The high atom-economical formation of indoles from anilines and diols was described with affordable and easy to handle Ni/SiO2-Al2O3. After optimization, 2,3-dimethylindole was isolated with an excellent 98% yield in neat conditions. The scope of the reaction was studied and 13 indoles were isolated in 16–80% yields.

An efficient and green synthetic method for the preparation of N,N-disubstituted tetramethylpyrazinium radical cations was developed, which does not require any solvent or strong alkylating agents. The investigation by UV/Vis and electron paramagnetic res
Heteroannulation of arynes with N-aryl-α-aminoketones for the synthesis of unsymmetrical N-aryl-2,3-disubstituted indoles: An aryne twist of Bischler-Moehlau indole synthesis

Reaction of 2-(trimethylsilyl)aryl triflates 1 with N-aryl-α-amino ketones 2 afforded N-aryl-2,3-disubstituted indoles in good to excellent yields with complete control of the substitution patterns. This methodology allowed for the first time a one-step s
