Abstract

Facile and one-pot synthetic route of poly-substituted pyrroles and 4-oxo-4, 5, 6, 7- tetrahydroindoles is established, which consists of three steps:(1) palladium-catalyzed oxidation of hydroxy-enamines by using tetrakis (triphenylphosphine) palladium and mesityl bromide oxidation system,(2) intramolecular cyclization, and (3) dehydration.
