摘要
A convenient and regioselective one-pot synthesis of 3-chloride or 3-bromide quinoline derivatives was achieved through a Grignard addition reaction by alkynyl Grignard regent to o-trifluoroacetyl aniline and a Cu(ll)-catalyzed cyclization-halogenation tandem reaction with aqueous HCl or HBr as electrophilic reagent.
