Copper-Catalyzed Aldehyde Exchanged Amidation

The synthesis of bioactive amides has been the pursuit of chemists. Herein secondary amides incorporated with an aldehyde group were first generated using aldehydes and secondary amines. Various (hetero)aryl aldehydes and even aliphatic aldehydes (>40 examples) were converted into the desired products in moderate to excellent yields (up to 89%). A plausible mechanism involving a Cu(I/II/III) catalytic cycle combined with radical rearrangement was proposed and confirmed with four key intermediates detected by high-resolution mass spectrometry.

Radical oxidation of amides and related compounds with hypervalent tert- butylperoxyiodanes: Synthesis of imides and tert-butylperoxyamide acetals

tert-Butylperoxyiodane undergoes oxidation of the methylene groups α to the nitrogen atom of amides (or carbamates) yielding imides or tert- butylperoxyamide acetals, depending on the reaction conditions. A proposed mechanism involves generation of carbon-centered radicals α to the nitrogen atom.
