|Title:||Najera oxime-derived palladacycles catalyze intermolecular Heck reaction with Morita-Baylis-Hillman adducts. An improved and highly efficient synthesis of alpha-benzyl-beta-ketoesters|
|Abstract:||An improved and highly efficient synthesis of several alpha-benzyl-beta-ketoesters from Morita-Baylis-Hillman adducts is described. These adducts were used as substrates for an intermolecular Heck reaction catalyzed by a Najera oxime-derived palladacycles. These efficient catalytic conditions probed to be very selective providing only the corresponding functionalized beta-ketoesters in high yield with no decarboxylation product. It seems that the method herein described is one of the most efficient for the synthesis of alpha-benzyl-beta-ketoesters. (C) 2009 Elsevier Ltd. All rights reserved.|
