Abstract
Pharmaceutical and chemical intermediates and related chemistry providing a green preparation method for quinoline compounds. N-Substituted arylamine derivatives as raw material react with arylacetylene or arylethylene derivatives for 24 hours at 80° C.-160° C. in the presence of Brønsted acid catalyst and oxidant without solvent, to obtain quinoline compounds. Beneficial characteristics include convenient operation, mild reaction conditions, environmentally friendly property and possibility of realizing industrialization, and provides the quinoline compounds in high yields. The quinoline compounds synthesized by this method can be further functionalized into various compounds which have potential applications in development and research of natural products, functional materials and fine chemicals.
