α-Alkylation of Ketones by Addition of Zinc Enamides to Unactivated Olefins.
— Intermediate zinc enamides, generated from the corresponding imines and bearing
an electron-donating xylyl group at the nitrogen, undergo a regioselective addition reaction to the more hindered carbon atom of the double bond of unactivated olefins to
give the corresponding γ-zincioimines. After protonation of the C—Zn bond and hydrolysis of the imine moiety with AcOH ketones are obtained in high yields (to be
continued). — (NAKAMURA*, M.; HATAKEYAMA, T.; NAKAMURA, E.; J. Am.
