Free-Radical Carbo-alkenylation of Enamides and Ene-carbamates
摘要:
The addition of xanthates and vinyldisulfones across the double bond of enamides and ene-carbamates provides access to the corresponding three.. component adducts in good to excellent yields with a high level of diastereocontrol in cyclic systems. This strategy illustrates a complementary reactivity for these versatile olefins and extends their scope of application.

In this Communication, we describe the construction of chiral α,β-unsaturated δ-lactams, widely used as pharmacophores, in high yields and excellent enantioselectivities using an oxidative relay Heckarylation reaction. This strategy also allows facile access to 7-substituted α,β-unsaturated ε-lactam products and δ-lactams containing a tetrasubstituted nitrogen-bearing stereocenter.

In this report, a palladium-catalyzed redox-relay Heck process to access optically active alkenylated α,β-unsaturated lactams is described. Under mildreaction conditions, electron-deficient alkenyl triflates and electron-rich alkenyliodoniumsalts undergo enantioselective and site-selective coupling with enelactams to deliver the products in high yields and excellent enantioselectivities. Furthermore
