Abstract:A series of 4-arylquinoline derivatives were obtained with high yields by thermal cyclization reactionusing N-arylphenylpropynylamine as a starting material and AgNO3 as the catalyst. Factors including solvents, catalysts, temperature affecting the cyclization yield were evaluated. Based on the experimental results, the best reaction conditionswereobtained.In this paper, the synthetic strategy had many advantages includingmild reaction condition, simple operation, and high yield and could be a novelmethod forthe synthesis of 4-phenylquinoline.
