A Highly Chemo- and Regioselective N-Acylative Alkynylation of Quinolines with Alkynylsilanes Promoted by Triflate Ion

Reactions of quinolines activated by phenyl chloroformate and silver triflate with 1-alkynylsilanes proceed smoothly at 83 °C to afford 1-alkynyl-1,2-dihydroquinolines in highly chemo- and regioselective manners.
