Bakers’ yeast catalyzed synthesis of polyhydroquinoline derivatives via an unsymmetrical Hantzsch reaction
摘要:
Bakers' yeast efficiently catalyzes the unsymmetrical Hantzsch reaction through a four-component coupling of aldehydes, beta-ketoesters, dimedone and ammonium acetate to form polyhydroquinoline derivatives in good to excellent yields. (C) 2007 Elsevier Ltd. All rights reserved.
