Indole derivatives

Gold-Catalyzed Reactions of 2-Alkynyl-phenylamines with α,β-Enones. —
title reaction offers a new, general approach to 3-alkylated indoles as well as
32- 124 The
1,2,3-trisubstituted indoles. Interestingly, starting from the propargyl alcohol (XI) and
ketone (V) only reaction with the solvent EtOH takes place and the mixed propargyl
ether (XIII) is obtained. Similarly, addition of H2O to substrate (XVIII) is observed
instead of indole formation with (V). — (ALFONSI, M.; ARCADI*, A.; ASCHI, M.;
