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.

The photoreductive cyclization of N,N-unsaturated dialkyl-beta-oxoamides produced delta-lactams in good yields. On the contrary the photoreductive cyclization of N,N-unsaturated dialkyl-beta-aminoketones produced substituted piperidines in poor yields.
