α-Substituted β-ketoamides were prepared in good yields by irradiation of a solution of 2-diazo-1,3-diketones, at 254 nm, in the presence of primary or secondary amines.

Cyclic enamines were oxidized by manganese acetate [Mn(OAc)3] and copper acetate [Cu(OAc)2] to produce α,β-unsaturatedimine, azadiene and aniline derivatives depending on the ring size.

Treatment of N,N-diallyl and N-alkyl, N-propargyl-β-ketoamides with NaH and then with N-iodosuccinimide led to the formation of iodomethyl- and iodomethylene-β-ketolactams.

Direct alpha-arylation reactions of secondary beta-keto amides with arynes, generated by fluoride-induced elimination of ortho-silyl aryltriflates, are described. The transformation proceeds via an interrupted insertion reaction of arynes and leads to densely functionalized aromatic compounds exhibiting a chiral 'all carbon' quaternary center under transition-metal-free conditions. An organocatalytic asymmetric version of the reaction also proved possible, affording the proof of concept that arynes can be involved in enantioselective transformations.
