Abstract:
Methods are provided for preparing bis-quinoline compounds, which include the steps of (1) condensing an aromatic 2-amino carbonyl compound and a methylene ketone compound to form an intermediate comprising a substituted quinoline having one chloro, one bromo, or one iodo substituent, followed by (2) reductive coupling of the quinoline, without its prior isolation or purification, using a transition metal catalyst, to thereby form the bis-quinoline compound.
