A Facile and Efficient One-Pot Synthesis of Substituted Quinolines from ,-Arylamino Ketones Under Vilsmeier Conditions

EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 24 2009
Yan Wang
Abstract An efficient one-pot synthesis of substituted quinolines from ,-arylamino ketones in the presence of PBr3 in DMF has been developed. This general protocol provides a novel and facile access to substituted quinolines by sequential Vilsmeier,Haack reaction, intramolecular cyclization and aromatization reactions of ,-arylamino ketones. PBr3 plays a dual role in the quinoline synthesis: as a key component of the Vilsmeier reagent (PBr3/DMF) and as a reducing reagent. (© Wiley-VCH Verlag GmbH & Co.
