Base-promoted domino reaction for the synthesis of 2,3-disubstituted indoles from 2-aminobenzaldehyde/2-amino aryl ketones, tosylhydrazine, and aromatic aldehydes

Substrate selective synthesis of indole, tetrahydroquinoline and quinoline derivatives via intramolecular addition of hydrazones and imines

A transition-metal-free, substrate selective synthesis of 2,3-diaryl indoles, 4-hydrazono-tetrahydroquinolines and substituted quinolines has been developed.
