Electrophile-driven copper-catalyzed one-pot synthesis of 3-halogen quinoline derivatives
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.
