ortho-Alkylation of Aromatic Ketimines with Functionalized Alkenes by Rh(I)
Catalyst. — The title reaction is described for a variety of olefins bearing functional
groups. Electron-withdrawing groups at the phenyl ring of the ketimines give a better
result than electron-donating ones. On the other side, the yield of ortho-alkylated products decreases with increasing length of the alkyl side chain in the imine substrates.Unexpected products are obtained in the reactions of (I) with N-methylmaleimide and
naphthalene (XIV) with (IIa). — (LIM, S.-G.; AHN, J.-A.; JUN*, C.-H.; Org. Lett. 6
