Synthesis of 3-aminoindole derivatives: combination of Thorpe–Ziegler cyclization and unexpected allylindium-mediated decyanation
摘要:
alpha-Anilinonitriles were unexpectedly converted to 3-iminodihydroindoles via the Thorpe-Ziegler cyclization during the benzoylation. 3-Iminodihydroindoles were transformed to 3-aminoindoles in good yields via an allylindium-mediated decyanative aromatization.

Trifluoroethanol is found to be an efficient and recyclable medium in promoting one-pot, three-component coupling reactions of aldehydes or ketones, amines and trimethylsilyl cyanide or trimethylphosphite to afford the corresponding α-amino nitriles or α-amino phosphonates in high yields. This protocol does not require the use of an acid or base catalyst.
