The sequentialimination and intramolecularpalladium-catalyzeddirectarylation of thiophene-3-carbaldehyde or furan-3-carbaldehyde with 2-haloanilines provided a one-pot access to furo- or thienoquinolines in high yields with H2O and HBr as the major waste. Both electron-withdrawing and -donating substituents on the 2-haloaniline derivatives were tolerated. These furo- or thienoquinoline derivatives
