A novelroute to electron-deficient thienopyrrolones is disclosed. The target heterocycles are concisely constructed by condensation of activated α- or β-halo-substituted acrylonitriles, or ortho-substituted halo, cyano heterocycles with mercaptopyruvate, followed by reduction and subsequent lactamization.
