Quinolines derivatives and their syntheses are of great interest owing to their broad applicability in areas from agriculture to medicine. This paper reports a simple method for the synthesis of quinolines from 2-aminobenzyl alcohols and β-dicarbonyl compounds in water. The reaction was easily performed in the presence of active manganese dioxide in air. A broad substrate scope with good functional group tolerance was observed. Furthermore, the corresponding quinoline products can also be obtained from 2-aminophenyl alcohols and acetophenone in water, choline hydroxide and active manganese dioxide as additives and heating at 50 ℃ are required. The method avoids the use of expensive and unstable aldehydes, and uses water as the solvent, making the process more economical and efficient.

Key words: quinolinone derivative, 2-aminobenzyl alcohol, active manganese dioxide, ketone, water
