Palladium-catalyzed tandem oxidative annulation of α-amino ketones leading to 2-aroylindoles
A simple synthesis of 2-aroylindoles via palladium-catalyzed tandem oxidative annulation directly from α-amino ketones has been developed. In this transformation, two-step reaction including oxidation of α-amino aetones to generate imine intermediates and
N-(2-Aminobenzylidene)-4-methylanilines - stable and cheap alternate for 2-aminobenzaldehydes: concise synthesis of 3-unsubstituted-2-aroylindoles
Abstract Synthesis of 3-unsubstituted-2-aroylindoles starting from readily available N-(2-aminobenzylidene)-4-methylanilines, cheap and stable alternative to 2-aminobenzaldehydes, and α-bromoketones was achieved in moderate to good yields under basic cond

Synthesis of indoles through highly efficient cascade reactions of sulfur ylides and N-(ortho-chloromethyl)aryl amides
Batting the ylides: A simple procedure carried out under mild conditions allows the direct and efficient synthesis of structurally diverse indoles. This approach involves a cascade reaction of sulfur ylides and N-(ortho-chloromethyl) aryl amides (see scheme). Copyright
SYNTHESIS OF 2-ACYLINDOLES FROM α-(N-ISATINYL) KETONES
2-Acylindoles were synthesized by the recyclization of N-phenacyl- and N-acetonylisatins in alkaline medium and the decarboxylation of 2-acylindolyl-3-carboxylic acids or their salts in basic or neutral media.
