A methodical mechanistic investigation allowed for the catalytic N-acylation of secondary cyclic amine counterparts by arylglyoxylic acids through radical-radical coupling. The reaction proceeds via a twofold SET-promoted Cu(I)/Cu(II) catalytic cycle under mild conditions. An analogous reaction variant allows for the N-acylation in a one-pot fashion directly starting from a secondary cyclic amine even in the presence of a second amine or hydroxy group.

A metal-free system has been discovered for the efficient α-oxygenation of tertiary amines to the corresponding amides using oxygen as an oxidant. This visible-light-mediated oxygenation reaction exhibited excellent substrates scope under mild reaction conditions and generated water as the only byproduct. The synthetic utility of this approach has been demonstrated by applying onto drug molecules. At the end, detailed mechanistic reactions clearly showed the role of oxygen and the photocatalyst.

SeO2mediated oxidative amidation of acetophenones, phenylacetylenes, and phenylacetaldehydes to α-ketoamides and aldehydes to amides is reported. Amidation selectively proceeds with secondary amines. α-Ketoamide derivatives of natural products 16-dehydropregnenolone acetate (8), pregnenolone acetate (10), and progesterone (11) were synthesized.
