SeO2 mediated 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.
