Cu/Pd cooperatively catalyzed tandem intramolecular anti-Markovnikov hydroarylation of unsaturated amides: facile construction of 3,4-dihydroquinolinones via borylation/intramolecular C(sp3)–C(sp2) cross coupling

An anti-Markovnikov hydroarylation of unsaturated amides via a Cu/Pd synergistically catalyzed cascade borylation/intramolecular sp2-sp3 cross-coupling has been disclosed. 3,4-Dihydroquinolinones, one type of important scaffold prevailing in pharmaceuticals and biologically active compounds, could be readily accessible with high regio-selectivity and high yields.
