Regiocontrolled preparation of 3-acyl-6-aryl-2-pyridones via condensation of 3-aryl-3-chloropropeniminium salts with β-keto-amides
摘要:
A series of substituted 3-acyl-6-aryl-2-pyridones have been prepared in one-step reactions via condensation of 3-aryl-3-chloropropeniminium salts with beta-keto-amides. This efficient synthesis has the advantages of high yields and simple reaction procedures. (C) 2010 Published by Elsevier Ltd.
