The palladium-catalyzed oxidation of hydroxy-enamines, which were obtained by the condensation of P-aminoalcohols and carbonyl compounds, proceeded to give the corresponding polysubstituted pyrroles and 4,5,6,7-tetrahydroindoles in good yields. The treatment of o-(2hydroxyethyl)aniline with the pall
