Based on the Tf2O-mediated intermolecular reaction of secondary amides with enamines derived from ketones, a novel approach to β-enaminones has been developed. The reaction is widely functional group tolerant and highly chemoselective. In the presence of 4 ? molecular sieves, the method can be extended to the one-pot condensation of secondary amides with ketones for NH β-enaminones synthesis.

Radical addition to enamines using Bu3SnH as reducing agent are reported (Schemes 2 and 4).The diastereoselectivity of these reactions was examined in different systems (Tables 1 and 2).Enamines derived from cyclic ketones such as cyclohexanone were alkyl
