KAl(SO4)2·12H2O catalyzed efficient synthesis of 3,4,6-trisubstituted 2-pyridone in water
摘要:
An efficient green protocol for the preparation 3,4,6-trisubstituted 2-pyridone of employing a condensation reaction of cyanoacetamide and acetylacetone in the presence of KAl(SO4)(2)center dot 12H(2)O in water has been described. The present procedure offers advantage such as shorter reaction time, simple workup, and excellent yields. (C) 2011 Majid M. Heravi. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
