In this paper we present our results concerning the rhodium/olefin-catalyzed reaction of arylboronic acids with an alpha-acetamido acrylic ester. With a chiral norbornadiene ligand rather low enantioselectivities (up to 21% ee) were obtained. Besides the expected conjugate adduct, we also observed the formation of a significant amount of Mizoroki-Heck-type product. The ratio of the conjugate adduct/Mizoroki-Heck product could be adjusted by a proper choice of the olefin ligand. (C) 2010 Elsevier Ltd. All rights reserved.
