Claim 1:
2. A method of synthesizing organic 7H-pyrano[2,3-b:4,5-b′]diquinoline derivative compounds, the method comprising:
adding 2-hydroxyquinoline-3-carbaldehyde to propargyl bromide in the presence of sodium hydroxide in n-propanol to produce 2-(prop-2-yn-1-yloxy)quinoline-3-carbaldehyde;
reacting the 2-(prop-2-yn-1-yloxy)quinoline-3-carbaldehyde with an arylimine in CH2Cl2 to produce a corresponding 2-(prop-2-yn-1-yloxy)quinolin-3-arylimine; and
treating the corresponding 2-(prop-2-yn-1-yloxy)quinolin-3-arylimine with about 20 mol % of boron trifluoride diethyl etherate (BF3O(C2H5)2) in 1,2-dichloroethane to produce the organic 7H-pyrano[2,3-17:4,5-b′]diquinoline derivative compounds.
